Pull Request description

makes the use of format and format-check targets easier for developers by doing exactly the same thing as on the CI side.
Would avoid format issue as in #891

Why did you add thirdparty into gitignore?

[bignaux]

i just added for thirdparty/clang-format-lint-action , to prevent git to list them as untracked files. btw ideally, external dependancies would be outside the OPL directory and shared between projects, but i don't want to go into this flamewar again if people are not interested.

[AKuHAK]

Doh, phone doesnt show me that it not folder but file, you are correct. Also, you hardcoded 12 as clang format version. Is it possible to somehow "latest" instead? I mean when they release 13 version, we dont have to update script.

[bignaux]

There is no "latest" and default is 9. Upgrading from 12 would make lot of file changes, wasn't the scope of this commit. If you want to go to 15, i could do another commit if you want.
