Add horizontal scroll to documentation

[ZitaNemeckova]

Fixes https://issues.redhat.com/browse/AAH-599

For https://cloud.redhat.com/ansible/automation-hub/repo/published/ibm/power_ibmi/content/module/ibmi_display_fix
Note: it looks really bad in standalone. In c.r.com you cannot read everything but left nav is visible.

Steps to reproduce:

• Create ibm namespace
• Upload https://cloud.redhat.com/ansible/automation-hub/repo/published/ibm/power_ibmi
• Go to that collection
• Select Documentation
• Select Modules
• Select ibmi_display_fix

If the idea is to just make sure the user can scroll to see the whole table, 👍, adding approve.

That said, I think the bug is really elsewhere.. galaxy_ng is the only place that generates a table that's too big to show.
The same content can be seen in the original documentation and on github, neither of which needs wrapping.

EDIT: we should consider not generating tables in the first place, but that's for another discussion

The code is right if the bug is really considered to be in the UI.
EDIT: it is 👍

(We could also set max-width and rely on wrapping instead of scrollbars, except that may break horribly on phones.)
