fix getting path parameter in undo operation

[MintsInc]

Context

BDD test undo operations fail when path parameters are needed from fixture-based resources (e.g., "there is a valid X in the system" steps). The build_given function creates fixtures but doesn't store path parameters needed for cleanup.

Changes

• Enhanced path parameter lookup in undo operations to try snake_case variant (to_parameter)
• Added path parameter storage in build_given for fixture creation
  • Identifies path parameters as required positional params (excluding "body")
  • Stores with all naming variants: original, snake_case, and symbol
• Enhanced "request contains" steps to store snake_case variant

Tests

Run BDD tests using fixtures with path parameters (on top of the changes generated by https://github.com/DataDog/datadog-api-spec/pull/4875). Verify undo operations find and use path parameters correctly.
