test: Improve node integration test running

[mydea]

This improves the output and formatting of the node integration tests, making it a bit easier to work with them:

1. Removed the coverage output, making the general output much clearer
2. Ensure we have color in the jest output, making it easier to scan it
3. Remove logging around started tests & workers, streamlining the output and aligning it more with the usual jest output.
4. Move skipped output to the end of the test, clearing up the output for actually run tests
5. Update summary at the bottom to show success/failed/skipped test numbers
6. Add color to summary output (error/success/skipped) to make it clearer.
7. Show relative path names instead of full path names

I also removed a bunch of debug: true leftovers in the tests, to clean up the output.

Much better - thanks a lot for tackling this!

One Q: Did anything change in regards to filtering to run a specific test (or subset of tests)? I guess the skipped tests will only be shown in the summary at the end?

[Lms24]

theoretically, we could use chalk or similar libraries for the color bytes but I think this is also fine

[mydea]

yeah, I thought about this as well - I think it is OK for now, if we want to do more with that we can always switch over to chalk!

So if a single test in a suite is skipped, it will be shown normally by jest. Only if all tests in a file are skipped will we show it at the end of the tests in the summary!

For reference, here you can see how it looks (with all successful tests): https://github.com/getsentry/sentry-javascript/actions/runs/7915325070/job/21606990771?pr=10673
