Galaxy meta docs table (#60171)

* Use an rst table instead of a raw html table

* Rst is easier to read so we want to use it wherever possible
* Fix the jinja2 filters which create links so that they do not include
  extraneous whitespace in the URL

* Normalize description data before sending them to the templates
