chore: bump go sdk generator to v7.24.0 (#288)

Update the Go-only openapi-generator-cli version from v7.22.0 to
v7.24.0, python and java stay unchanged.

The upstream go/client.mustache decode() function gained support for
decoding into *io.Reader and *[]byte, carried over into our
customized template.

Upstream also changed the oneOf "no match" error message, which
changed the generated AreaId models (iaas v1/v2/v2beta1) covered by
the override mechanism. Updated their hashes in overrides.properties
and adopted the improved message in the override files.
