Implemented validation logic for the webhook (#593)

* Fix workflow for autogenerating docs (#592)

* Use grep -c flag in check for changes step to fix case when more than 1 website file was modified

* Implemented validation logic for the webhook
- Created a single Validate() function to validate both updating and creating Jenkins CR.
- Implemented the Validate function to fetch warnings from the API and do security check if
  being enabled.
- Updated the helm charts and helm-e2e target to run the helm tests.
