Pull request overview

This pull request updates the unsupported operating system documentation to reflect that Debian 12 is no longer a supported option for running the Home Assistant Supervisor. The changes simplify the documentation by removing references to Debian 12 and the supervised installation method, clearly stating that only Home Assistant OS is now supported.

Key changes:

• Simplified "The issue" section to state that Home Assistant Supervisor is only supported on Home Assistant OS
• Streamlined "The solution" section to focus solely on reinstalling with Home Assistant OS
• Updated the restore process to reference the onboarding flow instead of the previous multi-step migration approach

[Copilot]

Missing comma after the introductory phrase. The sentence should read: "During Onboarding of Home Assistant, choose to restore from backup."

According to standard English grammar rules, introductory prepositional phrases should be followed by a comma when they provide context for the main clause.

Suggested change

	[Onboarding of Home Assistant](/getting-started/onboarding/) choose to restore from
	[Onboarding of Home Assistant](/getting-started/onboarding/), choose to restore from
