Our submodules seems to be out of sync quite often. This new action will automatically create a PR for updating the submodules once a week (could also do that more often if useful). In addition it's possible to trigger the action manually. This can be used before building a release.
Note: I've built this action to prevent having outdated submodules before a release is done. In the latest release the the log-analytics submodule for example was out of sync. Therefor a feature that was mentioned in the changelog actually wasn't included.
@sgiehl based on slack discussion will merge and see if it works, if not will revert and wait until 4.5.0
