ENH: Add `Styler.to_typst()`
- [x] closes #57617
- [x] [Tests added and passed](https://pandas.pydata.org/pandas-docs/dev/development/contributing_codebase.html#writing-tests) if fixing a bug or adding a new feature
- [ ] All [code checks passed](https://pandas.pydata.org/pandas-docs/dev/development/contributing_codebase.html#pre-commit).
- [x] Added [type annotations](https://pandas.pydata.org/pandas-docs/dev/development/contributing_codebase.html#type-hints) to new arguments/methods/functions.
- [x] Added an entry in the latest `doc/source/whatsnew/vX.X.X.rst` file if fixing a bug or adding a new feature.

I think this is a nice, minimalist implementation of `Styler.to_typst`, honouring some of the ideas in the original discussion. The coding mirrors the implementation for other formats in terms of signature and template composition.

Provided the tests pass I am supportive of adding this in. Would need a "whatsnew" Hi @attack68,
I have updated the "What's new". Could you please review it? @mroeschke want to have a second look? Thanks @3w36zj6
