Upgrade Docsy theme from v0.2.0-pre to v0.12.0 and enable dark mode

- Fixed corrupted Docsy submodule by removing and re-adding
- Upgraded through major versions: v0.2.0 -> v0.6.0 -> v0.10.0 -> v0.12.0
- Added missing SCSS variables for compatibility:
  * $td-sidebar-tree-root-color
  * $font-awesome-font-name
  * .-bg-orange utility class
- Removed Bootstrap 4 dependencies (switched to Bootstrap 5.3.3)
- Removed custom scripts.html override (conflicts with Bootstrap 5)
- Enabled dark mode via showLightDarkModeMenu = true

Dark mode is now available via the light/dark toggle in the UI.
