Checklist

• The pull request is for the branch main
• If I added new documentation related to a new Pull Request that I created, I have added a reference to the related Pull Request
  • N/A (documentation is for current PR, no future version note needed)
• If the additional documentation is a fix, you should directly push to the main branch and do not open this PR.
  → This is not a fix; it's new documentation for newly added analyzers, so opening a PR is correct.

Changes made:

• Added HibpBreaches and HibpPasswords entries to docs/IntelOwl/usage.md under Generic analyzers → External services, following the exact same format/style as the existing HaveIBeenPwned entry (including link to HIBP API docs).
• Added a short configuration subsection for both analyzers in docs/IntelOwl/advanced_usage.md under Analyzers with special configuration (covering API key requirement, dummy test key, domain endpoint limitations, optional parameters for HibpBreaches, and k-anonymity note for HibpPasswords).

@mlodic as per your comment in #3210:

changes are good, please open a PR for the docs too, as requested in the PR template. Once both are up and fine, I'll merge them together

I have now opened this docs PR with both usage.md and advanced_usage.md updated.

Please review and let me know if any changes, wording adjustments, or additional details are needed happy to fix anything right away!

Thank you!
