"int64" is intentionally converted as string in spec generation but format field is not generated at all. For other types like enum, when it is converted as string, format field is generated to indicate its true type. Same should be done for int64.
Example:
cmd/protoc-gen-openapi/examples/tests/protobuftypes/openapi.yaml:446
int64_value_type:
type: string
It should be:
int64_value_type:
type: string
format: int64
