Pull request overview

This PR fixes a bug in the JWT Authentication plugin where non-string claims (such as boolean values) could not be matched during authentication. The fix converts claim values to strings before pattern matching, enabling support for boolean and other non-string claim types as specified in the OIDC specification.

Changes:

• Modified claim matching logic to handle non-string claim values by converting them to strings
• Added test coverage for boolean claim matching scenarios
• Added changelog entry documenting the bug fix
