Switch to using autogenerated ChangeLog in docs

This commit switches the docs to use the PBR generated ChangeLog
instead of a hand curated release notes section. This is a lot less
error prone and instantaneous as compared to our current method which
often leaves the release notes section stale for months at a time.
