Add a utility script to bump supported OS versions

[smortex]

Add support for a newer version of an Operating System if the previous
version is supported. Update metadata.json, create a feature branch,
commit, and open a PR automatically.

If the previous version was not supported but older version are, prompt
the user interactively for what to do.

If the OS is not supported at all, do nothing.

Typical usage (when Debian 13 is released):

bundle exec msync execute -B -- git pull
bundle exec msync execute -B -- $PWD/bin/add-support-for-new-os -o Debian -v 13

I don't think this belongs in our modulesync config. I wrote voxpupuli/puppet_metadata#188 which already knows about which OS releases could/should be added.

There is msync exec for that. If it doesn't work, then we should enhance it so it does work.

operatingsystemrelease can be nil and it doesn't deal with that. This is also fragile because it doesn't handle a missing OS (typo).

If anything you should probably do something like:

Suggested change

	os_index = metadata['operatingsystem_support'].map { |os| os['operatingsystem'] }.index(options.os)
	metadata['operatingsystem_support'][os_index]['operatingsystemrelease'] << options.version
	os = metadata['operatingsystem_support'].find { |os| os['operatingsystem'] == options.os }
	unless os
	exit 1
	end
	if os['operatingsystemrelease']
	os['operatingsystemrelease'] << options.version
	else
	os['operatingsystemrelease'] = [options.version]
	end
