Support for flaky tests

[taman9333]

I have integrated GitHub Test Reporter into my GitHub CI. My application is written in Golang, and it has some flaky tests. I added the following job to detect flaky tests:

- name: Post PR Comment
  run: npx github-actions-ctrf flaky ctrf-report.json --pull-request
  if: always()
  env:
    GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}

However, I keep getting the following result:

No flaky tests detected. ✨

I suspect that the flaky flag might not be supported. Am I wrong?

It seems Flake flag does exist, but it's not evaluated or used

Hi @taman9333,
We would need to determine if a test has been retried reliably.

How are you retrying failed tests in Go?

Thanks

Hi! I would love this feature, since I have some codebases I work in which have some flaky tests. We are using what appears to be the standard (gotestsum with --rerun-fails) to re-run failures automatically, and it would be really useful if this tool could detect and report on them accurately according to the CTRF.io specification.

With that in mind, I've opened PR #28, which I coded up this morning, and added both an example (conditionally compiled) as well as some unit tests that use the output of that example. This is my first contribution, so please let me know if you have any questions or would like to see any changes. Thanks!
