Cockpit group should install app components instead of dependencies

[stevenlele]

archinstall/archinstall/default_profiles/servers/cockpit.py

Lines 15 to 16 in d43da6a

	def packages(self) -> list[str]:
	return ['cockpit', 'udisks2', 'packagekit']

According to https://wiki.archlinux.org/title/Cockpit and the cockpit package page:

• cockpit-storaged should be installed instead of udisks2
• cockpit-packagekit should be installed instead of packagekit

The components were split in https://gitlab.archlinux.org/archlinux/packaging/packages/cockpit/-/commit/1f0124c51f3951a4bd930d9028dca1702797be60 and ref cockpit-project/cockpit#19315.

Might be related to #4385.
