feat(proto): Regenerate Go protobufs for new IGDB API types

Regenerated `proto/igdbapi.pb.go` to reflect updates in the IGDB API schema.
This update incorporates new API types, such as `AgeRatingContentDescriptionType` and its corresponding result type.

The regeneration was performed with:
- `protoc-gen-go` updated from `v1.36.5` to `v1.36.10`
- `protoc` updated from `v6.30.1` to `v6.32.1`
