Extend selftest workflow to multiple runners

[norwd]

Please describe the change you are making

I'm condensing the existing self-test and self-test-macos jobs into a single job that defines runs-on with a matrix. I'm also adding windows to the OS list so that now there is also a test case for windows runners. This should help catch errors like #4 and #8 by ensuring that gotestfmt can run on all the major OS runners for GitHub Actions.

Your code will be released under the MIT license. Are you in the position, and are you willing to release your code under this license?

Yup :)

You can view an example run of the new workflow on my fork: norwd#1

Note that the MacOS job fails due to rate limiting because it's running in a fork and Windows fails due to #8. Once merged the MacOS job should run fine just fine, and once #8 is fixed ditto for Windows :)

Hmm, further experimentation shows that the runs: | script uses bash only feature that fail on the Windows runner. I'll update the PR with a pwsh version in the morning :)

Ok, I've refactored the workflow a bit so that the bash and pwsh scripts are separated (waayyyyy easier than trying to write a script that is simultaneously both vaid bash and valid powershell 😂). Now the only issue is that the Windows runner is still failing due to the error I reported in #8.

If you'd like to merge my changes now I think the new workflow still could be useful, the only thing that would be needed is changing the branch protection rules to require Self-test / on ubuntu and Self-test / on macos instead of on Ubuntu and on MacOS. Later on Self-test / on windows could also be added.

I've updated the workflow to use bash explicitly, as it is the default on Ubuntu and Macos, but on Windows pwsh is the default. I recently learned that the Windows runner also supports bash officially, which means my little workaround is not necessary 😄. Instead, all three runners now use the same bash script step.

Hi @norwd, thanks for your contribution! I really like the matrix to slim down the necessary code. I left two minor comments and as soon as they are resolved we can merge it, I'd say 😄
The gotestfmt-action does not work on windows at the moment - just as you reported in #8. I'll provide you with the details for the necessary changes in the issue if you are up for it 😉

Thanks @engelmi, I've applied your suggested changes. I'd be happy to look into solving #8 if you have any ideas?
