[wiki] Python 3.11 standard library `tomllib`

[Y.D.X.]

A version of Tomli, the tomllib module, was added to the standard library in Python 3.11 via PEP 680. (→ Tomli's README)

I think we should add it to the list in wiki.

1. Tomli is also in the list. Should we list them together?
2. The standard library does NOT support writing TOML. Does it fit the criteria? (Edit: Tomli does not support either.)
