chore: update required version for buf tool

The `buf` cli made a breaking change in `v1.32` [sic, 0], so we must
update the script invocations to keep it working. Touched up the docs
where appropriate, and ran the recommended `buf config migrate` cmd [1]
to get the files in sync with the new format. After rerunning `just
proto` on the migrated files, I see no changes.
