[Bug] container: missing stable-debug tag

[docgalaxyblock]

Is this a support request?

• This is not a support request

Is there an existing issue for this?

• I have searched the existing issues

Current Behavior

There is no :stable-debug tag available on docker hub and ghcr.

Expected Behavior

Having a :stable-debug tag

Steps To Reproduce

Try pulling the stable-debug tag

Environment

Not relevant for the missing docker tag

Runtime environment

• Headscale is behind a (reverse) proxy
• Headscale runs in a container

Anything else?

Could it be that here and here the line should be
- "{{ if not .Prerelease }}stable-debug{{ else }}unstable-debug{{ end }}"
and not
- "{{ if not .Prerelease }}stable{{ else }}unstable-debug{{ end }}" ?
