[Help requested] Only current branch for CI badge

[drwetter]

The file Readme.md displays a couple of badges. There are two badges for Github actions. Unfortunately both reflect the status of everything, i.e. also failed actions in PRs. So that a visitor gets the wrong impression (as right now).

The doc says that this can be solved by appending ?branch=3.2 to the SVG: https://docs.github.com/en/actions/monitoring-and-troubleshooting-workflows/monitoring-workflows/adding-a-workflow-status-badge . That doesn't work though.

If you have some cycles to spare and come with some knowledge, help would be much appreciated!
