fix(test): align local Typesense image with v30+ supported range

The integration spec at `spec/typesense/collections_spec.rb:156` expects
each field in the create-collection response to include `truncate_len`,
which was added to Typesense's field schema response in v30.x. The local
`docker-compose.yml` was still pinned to `typesense/typesense:29.0`, so
the spec failed locally with the field missing from the actual response:

    Failure/Error: expect(result['fields']).to eq(expected_fields)
    Diff: -  "truncate_len" => 100,

The README compatibility table already states typesense-ruby v5.0.0
supports Typesense >= v30.0, so this just realigns local development
with the gem's stated server compatibility.

Bumping to the latest stable patch (30.2) also surfaced two new fields
on curation rule responses (`stem`, `synonyms`); the curation set test
fixtures are updated to mirror them.

After the change:
- `bundle exec rspec` reports 151 examples, 0 failures, 16 pending
  (down from 27 pending: 11 specs that were skipped against Typesense
  29 are now exercised against 30.2).
