Fix PR link regexes after the move to react/react-native

[TheSeydiCharyyev]

Summary:

Two workflows stopped working after the move to react/react-native, because their regexes only allow github.com/facebook/react-native:

• Merged pull requests no longer get the release FAQ comment. Before the move, react-native-bot posted "This pull request was successfully merged by @author in sha" with links to "When will my fix make it into a release?" and "How to file a pick request?". The last one is on feat(ios): honor textDecorationStyle on Text decorations #56769 (June 9). Pull requests merged on October 15 (Combine the 0.88 RC sections into v0.88.0 #59122, Skip empty text decoration draws (#59050) #59050, Read only the drawn child's mix-blend-mode in Android drawChild #59016) only have the meta-codesync comment.
• Issues that link a pull request as the reproducer still get Needs: Repro. Examples: iOS: Text drops its last line when its box crosses y = 2048 on a 3x screen (Yoga float rounding) #58970, normalize-color accepts functional colors with surrounding junk #58495, TextInput claims the responder on every selection change, even with no active touch #58445, VirtualizedSectionList passes incorrect leading/trailingItem to ItemSeparatorComponent #55708. The bot's message for Needs: Repro asks for a pull request that edits RNTesterPlayground.js, but the bot does not accept a link to one.

Why

1. .github/workflows/close-pr.yml looks for Pull Request resolved: https://github.com/facebook/react-native/pull/N in the commit message. Commits now say https://github.com/react/react-native/pull/N, so getClosedPrIfExists returns undefined and the script stops before createComment. Update repository references from facebook/react-native to react/react-native #57167 changed the if: line in this file to react/react-native, but not the regex. The regex is written with escaped slashes (facebook\/react-native).
2. .github/workflow-scripts/checkForReproducer.js builds the pull request pattern in a template literal with single backslashes. In a template literal, \d is just d, so the pattern is https?://github.com/facebook/react-native/pull/d+/?. It did not match real links even before the move (the line was added in Update the reproducer message #50848). The other two patterns in the same function use \\ and work.

In the whole repo, facebook\/react-native appears only in these two lines.

Fix

Both regexes now accept facebook and react. People still write links with facebook: the four issues above all do. In checkForReproducer.js, the pattern now uses \\ like the other two patterns. (?:...) does not capture, so the group numbers in close-pr.yml do not change.

The new test file is checkForReproducer-links-test.js, so it does not conflict with checkForReproducer-test.js from #58429. That PR fixes a different problem in the same script: the bot treats its own Needs: Repro label as a maintainer change. Because of that, an issue that already has the label keeps it after an edit, also with this PR. New issues with a pull request link do not get the label.

Changelog:

[INTERNAL] [FIXED] - Fix pull request link regexes in the close-pr and check-for-reproducer workflows after the move to react/react-native

Test Plan:

Windows 11, Node 22.17.1, Yarn 1.22.22.

New Jest test for checkForReproducer with 4 cases: a link to a pull request in react/react-native, the same link with facebook/react-native, a pull request in another repository, and no link.

yarn test .github/workflow-scripts

Code	Result
main (e04aaf6)	2 of the 4 new tests fail: both pull request links are not accepted
this PR	11 suites, 72 tests pass

Each part of the fix is needed:

• facebook|react with single backslashes: both link tests fail.
• Double backslashes with only facebook: the react link test fails.

close-pr.yml runs an inline script, so it has no Jest test. I took prClosingRegex from the file and ran getClosedPrIfExists (copied from the file) on real commit messages from main:

Commit message	main	this PR
#59016: Pull Request resolved: https://github.com/react/react-native/pull/59016	undefined	59016
#56769: Pull Request resolved: https://github.com/facebook/react-native/pull/56769	56769	56769
"Update React Native DevTools binaries", no pull request link	undefined	undefined

npx prettier --check passes for the 3 files.

Not covered:

• I did not run the workflows. They run on push to main and on issue events in this repository.
• yarn lint does not check these files, because ESLint skips the .github folder.
