Description

Having merged Enum support into the query parameters, would it be possible to now support Enum Types in the path as well? Currently this appears to be limited by https://github.com/grpc-ecosystem/grpc-gateway/blob/fdcb7eab2d6ed4919e83ddcef4f199c161611e1f/protoc-gen-grpc-gateway/descriptor/types.go#L293 not being implemented for Enum types.

Research direction
The issue points to the file protoc gen grpc gateway/descriptor/types.go, specifically line 293 where enum handling is missing for path parameters. Investigate how enum types are currently handled for query parameters and replicate that logic for path parameters. Review the existing implementation in the same file for query parameters to understand the pattern, then extend it to path parameters.
