in 047ce136, we cherry-picked the change adding
garbage-collection-ics.rst to the document. but it was still
referencing the git sha1 and version number in enterprise.
this change updates kb/garbage-collection-ics.rst, so that it
* references the git commit sha1 in this repo
* do not reference the version introducing this feature, as
per Anna Stuchlik
> As a rule, we should avoid documenting when something was
> introduced or set as a default because our documentation
> was versioned. Per-version information should be listed in
> the release notes.
