chore: align release-please state with v3.0.1 tag (#691)

The v3.0.0 release-please PR (#648) merged and bumped the manifest to
3.0.0, but the v3.0.0 tag/release never got published due to the
immutable-releases fallout. v3.0.1 was hand-cut on top (commit ac75137)
with no manifest bump, so on-disk state has been drifting from reality:
manifest/package.json say 3.0.0 while the last real tag is v3.0.1.

With no v3.0.0 git tag to anchor against, release-please walked the
full repo history and proposed 0.12.1 in #690 (now closed). This PR
unsticks release-please by:

- Bumping .release-please-manifest.json, package.json, and
  PROVENANCE.md from 3.0.0 to 3.0.1 so they match the v3.0.1 tag.
- Adding last-release-sha pointing at ac75137... (the v3.0.1 commit)
  to release-please-config.json so release-please only considers
  commits after v3.0.1.

The Release-As footer below tells release-please to propose 3.0.2 on
the next run, since the only commits between v3.0.1 and HEAD are a ci:
change (#689) and this chore, neither of which would trigger a bump.

v3.0.1 ships as a ghost release with zero assets attached (all prior
manual-publish runs against it failed on immutable releases), so
v3.0.2 will be the first real 3.x release with binaries and
actions/attest provenance under the new flow from #689.
