gh-136428: amend UUIDv8 performance improvements (GH-136903)

UUIDv8 has been added in Python 3.14.0a2 and its construction time
has been improved in Python 3.14.0a4, but since those changes will
not be visible when comparing the latest Python 3.13 and 3.14 together,
we do not document them on the What's New page to avoid confusion.
(cherry picked from commit 5798348a07)

for 16-byte names and 20% faster for 1024-byte names. Performance for
longer names remains unchanged.

respectively.
