Add description to parameter info inside Jinja template for EDR HTML pages

[C-Loftus]

Is your feature request related to a problem? Please describe.

EDR contains an optional description in the parameter list for each parameter. This was added by pygeoapi in #2234 which closed #2233

If the description is present, it may make sense to show up in the HTML for debugging / exploration purposes since it provides a helpful natural language description.

Describe the solution you'd like

A 4th column could be added to the end of the query param table with the name description.

Describe alternatives you've considered

Description is optional. If no parameters for a given collection set description it would be possible to drop this column entirely from the HTML view. However, I am not sure if that is potentially confusing.

Additional context

I'd be happy to implement this myself and make a PR.
