Use pre-commit action against merge-base

Resolve https://github.com/hofbi/telecarla/pull/32/files#r803870102 and https://github.com/hofbi/telecarla/pull/32/files#r804069423

Caching works just fine with the action! In the first passing run, pre-commit required 55s, in the run after that only 20s 🎉

@hofbi let's have pre-commit integration even nicer, as e.g. at CLIUtils/CLI11#689. Can you authorize github at https://pre-commit.ci/ and add pre-commit ci to this repo?

[hofbi]

Ok, done.

To trigger the CI you could also update https://github.com/hofbi/telecarla/pull/33/files#diff-b803fcb7f17ed9235f1e5cb1fcd2f5d3b2838429d4368ae4c57ce4436577f03fR15 to v2 and add the pre-commit.ci badge to the readme.

Badge done, what exactly do you mean with the v2 part?

[hofbi]

Is this one ready?

[cbachhuber]

Yes, except the v2 thing that I didn't understand.Is that resolved?
