Run tests with GitHub Actions

[abitrolly]

There are a couple necessary fixes with dependencies. Basically it my experience takes a few hours to setup the project and report one of the issues.

The tests fail with this problem.

Can't use 'defined(%hash)' (Maybe you should just omit the defined()?) at /home/runner/work/explainshell/explainshell/tools/w3mman2html.cgi line 223.

Which can be repeated without the test suite.

/home/runner/work/explainshell/explainshell/tools/w3mman2html.cgi "local=%2Fhome%2Frunner%2Fwork%2Fexplainshell%2Fexplainshell%2Fmanpages%2F1%2Fxargs.1.gz"

This fix is proposed in https://github.com/idank/explainshell/pull/212 but I am not proficient in Perl to review it.

Merging this PR will at least allow to see if other PRs do good without executing them locally.

This looks really nice. Do you mind cleaning the commits a bit, remove the debugging one and squash ones that are basically fixing bugs in the changes?

I merged #212 .

@idank squashed a bit. Installation and linting works without problems, but tests fail for some reason. Maybe because I had to upgrade NLTK, I don't know.

Let's skip those tests then. I don't think they're that important since we're not using that code.

@idank all green now - https://github.com/abitrolly/explainshell/actions/runs/3213172763

[idank]

Thanks! The commit that bumps nltk can be removed since I merged https://github.com/idank/explainshell/pull/244, do you mind fixing that?

Also if it's not too much trouble can you change the commit summary to follow the style of subject: summary, e.g. tests: integrate with github actions.

[abitrolly]

Yup. Lemme rebase that.

[abitrolly]

@idank done!

[idank]

Merged, thanks! :)
