typing standard library documentation misses tags "New in version 3.11."

[Dutcho]

Documentation

In version 3.11.0a7, the typing standard library documentation typing.LiteralString misses tag "New in version 3.11." although the feature was listed in "What's New" issue 91491.
The same applies for typing.Unpack.

PEP 655's Required and NotRequired are mentioned in the "What's New" issue, but don't exist yet (in version 3.11.0a7) in either the typing module or its documentation. When that issue's resolution gets merged, and the typing documentation gets updated, these need the tag "New in version 3.11." too.
