Evan Mattson ac5c37e442 Python: Allow hyphens in function param metadata which are sometimes present with MCP plugins (#12267 )

### Motivation and Context

We recently relaxed the regex for `FUNCTION_NAME_REGEX` and
`FULLY_QUALIFIED_FUNCTION_NAME` to allow hyphens, which are sometimes
present while using MCP. However, we did not include a relaxed Regex for
`FUNCTION_PARAM_NAME_REGEX`, which was still causing errors while using
MCP within SK.

This PR relaxes the regex for `FUNCTION_PARAM_NAME_REGEX` so that there
are no errors while using MCP.
