doc: rm reference to old Ubuntu release

Remove the reference to "Ubuntu 12.10" since this is EOL.

Clarify that we only recommend Ubuntu LTS releases.

(Since this information has a tendancy to become stale, perhaps this
whole paragraph should be removed here and we should simply point at the
main OS Recommendations page.)
