Pull request overview

This PR adds support for enum types in array encoding for the Python HTTP client generator. It addresses issues #9404 and #9026 by updating the deserialization logic to handle delimited arrays containing enum and extensible enum values.

Changes:

• Updated @typespec/http-specs dependency from 0.1.0-alpha.31 to 0.1.0-alpha.32-dev.1 to include new test specifications
• Added comprehensive test coverage for enum and extensible enum array encoding with various delimiters (comma, space, pipe, newline)
• Refactored _deserialize_sequence logic in model_base.py.jinja2 to support union types containing array-encoded deserializers
