Summary description: Coloured boxes, for LaTeX examples and theorems, etc

Announcement text:
----------------------------------------------------------------------
### Added
- Library `documentation`:
- Option `page ref formatter` (issue #273)
- First experimental partial tagging support: suppress tagging of drawing (issue #283)
This works for lualatex only.

### Changed
- The base package loads `tikz` now instead of `pgf`.
All skins, including the `standard` family, use `tikzpicture` as internal environment now.
- Boolean marker to detect if inside a `tcb@savebox` introduced (issue #262)
- LaTeX usrguide cited for `\NewDocumentCommand` and friends (issue #263)
- Stricter checks on box names in `\newtcbox` and friends (issue #264)
- Checks on formatter like `index key formatter` enforced (issue #265)
- Needed LaTeX version updated to 2023-11-01
- More meaningful error message in case of `\DeclareTColorBox` with same auto counter (issue #276)
- Library `theorems`:
- Options `ams align`, `ams align*`, `ams gather`, and `ams gather*` are now shortcuts
for the upper part only (issue #282)
- Documentation for `ams align`, `ams align*`, `ams gather`, and `ams gather*` adapted, i.e.
exclusion of lower parts documented (issue #282)
- Technical information: The package documentation is now produced with lualatex instead of pdflatex

### Deprecated
- The option `graphical environment` is useless now, since all environments are based on `tikzpicture` now.

### Removed
- Documentation for the deprecated options `before example` and `after example`
- Documentation for the deprecated option `graphical environment`

### Fixed
- `\@nobreakfalse` added to `\tcb@parbox@false@settings` to avoid
decreased space before list with `parbox=false` following a section heading (issue #270)
- Documentation typos fixed (issue #279)
