Describe the issue

While looking through the documentation, I noticed our documentation still refers to jquery-bootgrid for our grids (https://docs.opnsense.org/development/frontend/view_js_helpers.html#uibootgrid), since we're now more or less finished with the migration to tabulator it feels like a good time to update and extend that part of the docs.

Suggestions

Update and describe standard handles we offer now.
