doc/start: update documenting-ceph branch names

This PR updates the branch names in the
documenting-ceph.rst file. It gets rid of all references
to the "master" branch, and updates the language to
reflect the state of play in 2022.

inb4: This PR merely removes the most egregious inaccuracies,
the ones that were most readily evident on a cursory perusal.
The full text remains to be carefully read and fitted together
with care.

I had to start somewhere.

+Location of the Documentation in the Repository
+===============================================
+
+The Ceph documentation source is in the ``ceph/doc`` directory of the Ceph
+repository. Python Sphinx renders the source into HTML and manpages. 
+
+Viewing Old Ceph Documentation
+==============================
+The https://docs.ceph.com link displays the latest release branch by default
+(for example, if "Quincy" is the most recent release, then by default
+https://docs.ceph.com displays the documentation for Quincy), but you can view
+the documentation for older versions of Ceph (for example, ``pacific``) by
+replacing the version name in the url (for example, ``quincy`` in
+`https://docs.ceph.com/en/pacific <https://docs.ceph.com/en/quincy>`_) with the
+branch name you prefer (for example, ``pacific``, to create a URL that reads
+`https://docs.ceph.com/en/pacific/ <https://docs.ceph.com/en/pacific/>`_).
