fix+release(3.2.1): build the gem from THIS repo at the tag; bump 3.2.1

The release workflow checked out the monorepo and shipped the
monorepo's ruby/ tree — the v3.2.0 gem on rubygems does not contain
this repo's decode fixes (512-step cap, UTF-8 scrub). 3.2.1 ships
them: the workflow checks out the tagged ref, runs this repo's suite,
builds from its gemspec, publishes via the API-key secret.
