config: singular ANSIBLE_COLLECTIONS_PATH (#70007)
* config: singular ANSIBLE_COLLECTIONS_PATH

Every other *_PATH setting in ansible is singular, and the traditional
$PATH variable is also singular despite containing a list of
directories.  Let's be consistent both internally and with POSIX
tradition.

* update all ANSIBLE_COLLECTIONS_PATHS env references to be singular

* deprecate plural ANSIBLE_COLLECTIONS_PATHS setting
