fix: update gRPC stream type display labels in ApiEndpointDocumentationElement

- Modified the display logic for gRPC stream types to use simplified labels (UNARY, CLIENT, SERVER, BIDIRECTIONAL) instead of the previous capitalized format.
- Updated corresponding test cases to validate the new label format for gRPC stream types.
