grntest 1.7.7: 2024-11-12

Improvements

• Required json 2.8.1 or later. Because json 2.8.0 changed
  JSON.pretty_generate result.
  • Note that this broke existing tests. We need to update
    .expected contents with new output.

grntest 1.7.6: 2024-09-25

Improvements

• #@require-os: Added to run tests only when Groonga is built for
  the given OS.
