Fix Forgejo hostname resolution: set GITHUB_SERVER_URL to reachable address

The runner container cannot resolve 'forgejo' Docker hostname.
Set GITHUB_SERVER_URL to the accessible URL (10.100.0.2:3000).

- Add FORGEJO_URL env var (defaults to http://10.100.0.2:3000)
- Override GITHUB_SERVER_URL for checkout action
- Can be configured via vars.FORGEJO_URL in Forgejo settings
