Make plugin list in PDF docs readable (#9241)

The current PDF docs attempt to format the list of all plugins as a
table, without any word-wrapping of the plugin description. That results
in almost all the information getting cut off. This PR formats the same
information into more of a paragraph format for the PDF, with nothing
cut off.

Fixes #451
