Fixes parts of #8135
- Fixed rendering of the documentation panel when no entry is selected.
- Multiple improvements of tags in the documentation panel:
- Group color for `GROUP` tag
- Custom styling for `DEPRECATED`, `UNSTABLE`, and `ADVANCED` tags.
- Sorting
- Collapsing tags that exceed one line with a button
- Filtering out some tags (`ICON` and `TEXT_ONLY` for now)
- Filtering out private items from the documentation
- Fixing group colors (was incorrectly assuming unique group names) and fallback color (was incorrectly replacing every character in the name with `-` before hashing, which was hilarious).
- Fixing ComponentBrowser demo scene.
- Minor fixes for mock database in demo scenes (removed duplicated entry, added an additional one for testing tags)
