[JENKINS-74907] Add validations when Jenkins is in FIPS mode

[jmdesprez]

PR to improve plugin's FIPS compliance. All the checks are centralized in FIPS140Utils to ensure consistency of error messages.

Bump of Jenkins is required to have access to FIPS140.useCompliantAlgorithms()

Testing done

See added unit tests. Here is also screenshots from the form validation:

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

I'm fixing the unit test

It's not possible to tests this because of non-compliant dependencies. So I'm moving this PR to draft.
