[PATCH docs 2/4] pve-storage-cephfs: describe CephFS, not RBD, in external cluster setup

[Kefu Chai <k.chai@proxmox.com>]

The "external Ceph cluster" section of the CephFS chapter describes
configuring "external RBD storage" in both the CLI and the GUI
walk-throughs. Refer to CephFS there instead - this was likely a
copy-paste leftover from the RBD chapter.

 The secret is only the key itself, as opposed to the `rbd` backend which also
 contains a `[client.userid]` section.
