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

picnixz · web-flow · commit 5798348a0739 · 2025-07-21T08:23:16.000Z
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.
