Bump version to 0.32.0-beta.2

In preparation for doing another RC release bump the version and
update the lock files.

The changes in this release do not need a changelog entry because they
are:

- Remove `doc_auto_cfg`
- Re-order args in deprecated method we just added already (changelog
  mentions it already).
