Added Langcheck __version__

See Issue #74

By the way, the current head (v0.9.0) is failing the pyright test mentioned in the contribution guide, due to a problem in metrics/eval_clients/_gemini.py
I think it might also make sense to pin the Python version for this repository, as some of the dependencies do not work with the latest Python version.

Thanks for your contribution, @matchcase!!

The change LGTM, could you also add changes to this section so that we don't forget to update the version string?

Also thanks for reporting the type error, seemingly it is because the interface exposed to the type checkers changed in the latest google-generativeai library. Code behavior didn't change, so I think no need of making a new patch release, but separately working on that in #174 .

I'll approve the PR and merge it into main once the doc is updated and the type error is resolved with #174 !!

Hi @liwii,
Awesome, I've added the step in contributing.md!
I was wondering if there are any other issues (perhaps more challenging ones) that I could try working on?

[liwii]

Thanks a lot, looks perfect!!

We're differently welcome for more contributions!! Is it okay for us to look around the issues and get back to you in a few days? (There are also some undocumented ones I think)

[matchcase]

Sure, that works!

[liwii]

Approved! Thanks a lot for the contribution!!

[liwii]

As for the new project, I mentioned you in #175 and #176, so let's discuss there!!
