feat(aws-lambda): Add Lambda runtime resource attributes

[pabloDeputter]

Description

Expand aws-lambda instrumentation with extra resource identity and runtime metadata following OTel (https://opentelemetry.io/docs/specs/semconv/faas/aws-lambda/).

Changes:

• add sentry.kind=server.
• add cloud.account.id, extracted from the invoked function ARN.
• cloud.resource_id is now normalized from the invoked function ARN; keep the original value in aws.lambda.invoked_arn and replace an alias with the resolved published version when the function is not $LATEST.
• cloud.region is now extracted from AWS_REGION env. var; faas.name from AWS_LAMBDA_FUNCTION_NAME; faas.version from AWS_LAMBDA_FUNCTION_VERSION following OTel (https://opentelemetry.io/docs/specs/semconv/faas/aws-lambda/#resource-detector).
• refresh sentry_sdk on every test setup (for easier local testing so runs don’t reuse old behavior from earlier implementation).
• add capture_internal_exceptions() around attribute extraction so that a single failure does not affect the other instrumentation.

See comment 🙏🏻

We can't make requests from the SDK. We need to only work with what we can intercept from the natural execution of a user's program without creating side effects like network or DB traffic that are not necessary for making the SDK work (e.g. sending events to Sentry).

Can we get this info from elsewhere? If not, let's not add it.

ok yeah makes sense, didn't think about this.

It's not really available anywhere else, so I'll remove it.
