Description

Similar to #1347, it would be good to also add support of enums in path parameters.

One additional requirement: It would be good if multiple query and/or path parameters actually reference the same enumeration, that only one enumeration is generated and is then being referenced from all places where it was defined.

Research direction
Review how enum support was implemented for query parameters in the referenced issue #1347. Examine the Java generation templates (likely in modules/swagger codegen/src/main/resources/) to understand path parameter handling. Identify where enums are currently handled for path parameters and adapt the approach from query parameters, ensuring deduplication of identical enums across multiple parameters.
