(CI) use newer lint action

[MatthijsBurgh]

Current one fails to run, but this doesn't show because of settings

The new action allows for checking only updated files in a PR. When we would do that, we could remove the continue-on-error. And enforce the linting on updated files. Which would slowly increase the linting on the entire rulebook.

Disabled this via:
#937

The bot does not react correctly on updates on the pull request branch which means people have to manually dismiss bot reviews.
This is too confusing for contributors.

[MatthijsBurgh]

But the current version is broken, j2kun/chktex-action#40

So I suggest to use the new version, but always check all files. So the behaviour doesn't change. But at least it works again.

[LeroyR]

The new version uses a Github bot setup to automatically suggest changes but will not update them: thus it opens change requests and blocks all pulls which then require manual intervention.

We ignored the output anyway. We can remove the action for now.
I am open to enable this again after all checks pass to test that behavior again.

out of date

I will do some tests to check whether we can disable the review functionality
