refactor: improve gitea installer

- Refactor the Gitea installer to use a more robust and.
- configurable approach.  The installer now uses a more.
- flexible configuration system and handles different.
- platforms more effectively.  The installation process.
- is now more modular and easier to maintain.  The.
- previous method was overly simplistic and lacked.
- essential configuration options.
