[JENKINS-73904] Enable FIPS restrictions in the JWK signing algorithm for Token verification

[fcojfernandez]

Based on #424 as there seems to be issues to push commits

(merits for @pankajy-dev)

See JENKINS-73904 -> When Jenkins is running on FIPS mode then the algorithms are filtered. Non accepted algorithms are not used.

Testing done

Submitter checklist

• Make sure you are opening from a topic/feature/bugfix branch (right side) and not your main branch!
• Ensure that the pull request title represents the desired changelog entry
• Please describe what you did
• Link to relevant issues in GitHub or Jira
• Link to relevant pull requests, esp. upstream and downstream changes
• Ensure you have provided tests - that demonstrates feature works or fixes the issue
