This PR is related to ansys/ansys-templates#92.

Notice this is not a Python project but still takes advantage of pre-commit andtox.ini for automation.

Vale will be implemented in a separate PR. I expect lots of warnings comming from this tool as this project has lots of doc content.

Not sure where these "docs_build" and "pre-commit checks" are comming from...

LGTM! =)

It was coming from a branch rule mainly, once you changed the step names, the rules didn't update automatically. I just updated it. No worries anymore.

I remember protection rules for main branch were discussed some time ago. From private discussion, this is something we need to enable in the settings section.

As @RobPasMue, this condition should be spread to other projects in the ecosystem.

I'll take a look to https://github.com/jcwilson/git-hooks/blob/master/included/pre-commit-protect-branch.

We may also have the possibility to implement branches protection locally.
