Remove actions for pushs

[tbauriedel]

At the moment workflows are triggered for PRs and pushs.

The workflow to contribute says that a PR must be created beforehand for each contribution into main.
For this reason (and to avoid duplicate workflows), github workflows should only be triggered for PRs.

I have also checked this branch before creating the PR. No workflow were scheduled.

Fixes #302

Looks good. I'll let pipelines run and check if everything works as expected. Maybe, when all succeeded we can do another push and try of they still work? The both of us are quite sure that it will work but this might still help with finding unexpected behaviour.

I have also enabled that the linter will run always.

Sure. You can start one after that.
If something is missing, I can check that again.

When everything's done, I'll just update the branch from main. We should then see if they run again. If they do, I'll approve. This should speed up checks again (by a lot)

Works ;)

Pipelines work as expected, now. Thanks!
