chore: Rename 'py' to 'pytest' in GHA to avoid confusion

[MaxymVlasov]

Description of your changes

When you see py in tests it not clear what exactly going on. Until now I thought that it represents "python", but actually this part run pytest

So, for avoiding confusion and add ability to explicitly specify tox r -e pytest, this PR was made

How can we test changes

Wait till tests pass on this PR

Wow, 56 tests 😲

I also think we should ask @webknjaz to also review and approve Py-based PRs here to get his knowledge work for us 😄

Rename at least in GHA view works fine, but some tests failed, idk why. Rerun doesn't help
@webknjaz I see that these test runs on ubuntu 24.04, when prev were on 22.04. Could it be the reason why it failed? In other 2 PRs for test also used ubuntu 24.04, but their tests passed 🤔

The "Download all the dists" step got skipped and the following job couldn't install the expected wheel artifact for testing, crashing the job. The rest were auto-cancelled due to fail-fast in the matrix.

It's possible their past platform issues haven't been fully resolved: https://www.githubstatus.com/history. Give it time and restart in the morning.

The root cause is that this part hasn't yet been made reusable: https://github.com/antonbabenko/pre-commit-terraform/blob/5181957/.github/workflows/reusable-tox.yml#L265C52-L265C56. You'll need to add the new name to the hardcoded list there, for now.
