docs: normalize legacy server product name to "ownCloud Classic" (#1268)

* docs: normalize legacy server product name to "ownCloud Classic"

Rename the legacy ownCloud server product to its canonical name
"ownCloud Classic" across all user-facing documentation text. The
version (10/11) is kept only as trailing information where relevant
(e.g. "ownCloud Classic 10").

Normalized variants: "ownCloud Server", "owncloud Server",
"ownCloud Classic Server", and bare "ownCloud 10/11".

Scope is limited to prose, headings and link display text.
xref/include targets, module slugs (classic_ui, oc10-app), URLs,
attribute names (e.g. oc10-api-url), image paths, anchors, and the
new product names (ownCloud Infinite Scale / oCIS) are unchanged.

Verified: every URL/xref target byte-identical and oCIS/Infinite
Scale occurrences unchanged.

Part of owncloud/docs#5111

* docs: drop redundant "10" version and fix grammar after rename

Two follow-ups to the "ownCloud Classic" rename:

1. Strip the now-redundant "10" from bare "ownCloud Classic 10"
   references where the version carries no meaning. Specific release
   references (e.g. "ownCloud Classic >= 10.8") keep their version.

2. Where replacing the noun "Server" with the adjective-final
   "Classic" left a dangling sentence, restore the common noun
   ("...used with an ownCloud Classic server.").

xref/include targets, module slugs, URLs and oCIS / Infinite Scale
references are unchanged.

-Compared to the apps/extensions in ownCloud 10, the Infinite Scale extensions/services are more secure because they are developed and deployed as standalone services.
