Enable "format check" workflow for push to all branches

[astrogeco]

Is your feature request related to a problem? Please describe.
The format check workflow only runs for pull requests or for pushes to "main" so it will not run on work done in forks.

Describe the solution you'd like
Remove branch restriction for "push" trigger and add "check for duplicates" job

Describe alternatives you've considered
None

#317 switched to use the shared workflow, so this is no longer applicable.
