andrewdotn bcad6e8e9a 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

Plugin List
===========
PyPI projects that match "pytest-\*" are considered plugins and are listed
automatically. Packages classified as inactive are excluded.
.. The following conditional uses a different format for this list when
creating a PDF, because otherwise the table gets far too wide for the
page.
