Hypothesis version 6.152.10

This patch renames our source code directory from "hypothesis-python"
to "hypothesis", and changes our canonical scheme for git tags from
"hypothesis-python-X.Y.Z" to "vX.Y.Z".

We have backfilled git tags in the new "vX.Y.Z" scheme. Any
distributions or build scripts which rely on the git tag scheme should
update to the new scheme.

The canonical version of these notes (with links) is on readthedocs.
