chore: update CI Node versions and remove Node 22 support (#5)

* chore: update CI to run on active Node versions

* fix: fix test script

This was failing in Node v22 maybe because of a syntax change

* chore: remove Node 22 support

Tests were failing on Node 22. Easiest solution is probably to wait until we update to ts-proto@2 on mapeo-schema, so we can update here too, which switches to use @bufbuild/protobuf which should better support Node 22
