Add changes from master

[leifg]

There have been a couple of PRs that have been merged into master instead of main.

It looks like releases are built from main so all these changes did not make it into the release.

Ideally we add these changes and release a new version.

Additional context. I needed some changes to make CI pass:

Use latest version of JRruby (same minor, different patch)

Correctly implement stderr spec:

The BackticksRunner and PopenRunner doe not support outputs on stderr, therefore the spec that verifies whether large output on stderr hangs or not, doesn't make sense for these runners.

The only reason it works on MRI is because the way the spec is written, selects the ProcessRunner.

On JRuby the ProcessRunner is not supported, so it falls back to the BackticksRunner and then makes the spec fail.

@cpytel is that something we can get released?

Thanks for opening this — I'm taking a look, and might break your PR out a bit in the process because it seems we've made a mess here.

I've taken everything here and broken it out into a set of different PRs:

• Don't hang on stderr: Don't hang on stderr #41
• Insert an inspect on the status: Insert an inspect on the exit status #42
• Upgrade JRuby: Upgrade JRuby to 9.4.12.0 #43
• Upgrade actions/checkout from v2 to v4: Upgrade actions/checkout from v2 to v4 #44
• Add Ruby 3.3, 3.4 to the build matrix: Add Ruby 3.3, 3.4 to the build matrix #45
• Fix the stderr test: Fix the stderr test #46

There's a few other bits I'm noticing, so I'm going to check those first, but then I'll cut a new release.
