Badges should point to the repository's `main` branch in the `Action` tab

[thewtex]

As reported by @jhlegarreta, the Build, test, package badges' links point to an SVG file across many (all?) remote modules (maybe also in the ITKModuleTemplate). I'd dare to say that this is not really helpful: IMHO they should point to each repository's master branch in the Action tab e.g.:
https://github.com/InsightSoftwareConsortium/ITKIOFDF/actions/workflows/build-test-package.yml?query=branch%3Amaster
