Update PEP 693 with the actual date of 3.12 beta 1, and delay beta 2 by a day to not conflict with Memorial Day and Pentecost.

…#3151)

From Python 3.12, datetime.datetime.utcnow and
datetime.datetime.utcfromtimestamp emit deprecation warnings.

* Improve PEP 649's description of its semantics.

* Stipulate that name resolution for annotations
  under 649 must be *identical* to stock semantics.
* *Don't* specify exactly the mechanism that conformant
  implementations must use to implement 649.  Instead,
  *do* describe how CPython might do it, but leave the
  actual details of how to implement 649 up to each
  language implementation.
* Incorporate Jelle's suggestion that the formats for
  inspect.get_annotations() be in an enum.IntEnum.

* Fix lint.

* PEP 693: Postpone 3.12.0b1 by two weeks (#3139)

* PEP 695: Lazy evaluation, concrete scoping semantics, other changes (#3122)

- Lazy evaluation means that referencing a later type variable works at runtime
- Disallow walrus in TypeVar bounds, and also disallow yield/yield from/await
  in the same contexts
- Remove rejection of lambda lifting; that is the implementation we are using now
- Change the AST
- Change of direction on mangling
- More precise scoping rules

* Incorporate changes from feedback, mark Accepted.

* Fix PEP 12 header *order compliance*.  Wow.

* Fix Sphinx complaints.

* Make enum consistent, flesh out observed semantics.

* Add "Resolution" header, as pointed out by Hugo.

* Switch to other URL for Resolution header.

* Apply ``global_enum`` to ``inspect.AnnotationFormat``

* Final? text / semantics cleanup pass.

* "accept" -> "accepts".  Bettering my Englishes.

* Add new "post history" reflecting the updates.

* Update post history with all conversations, courtesy CAM!
