Updates help center, integration and contributor docs where for
the new subsections on the organization settings tab, which were
changed in #33605.
Previously, these settings were all in the "Other settings"
subsection for that organization settings tab.
'Quote message' is a more accurate decription, as this option inserts
the quoted text into whatever message you're composing or editing;
it does not necessarily start a new reply.
Fixes first part of #31953.
Dropping support for url_prefix for RealmPlayground, the server now uses
url_template instead only for playground creation, retrieval and audit
logging upon removal.
This does the necessary handling so that url_template is expanded with
the extracted code.
Fixes#25723.

These files are not Jinja2 templates, so there's no reason that they needed
to be inside `templates/zerver`. Moving them to the top level reflects their
importance and also makes it feel nicer to work on editing the help center content,
without it being unnecessary buried deep in the codebase.
