Trivial: Update HPA description (#9711)

Browse Source 
* Trivial: Remove unnecessary new line

Current HPA page[1] contains unnecessary new line between
"metrics.k8s.io" and "custom.metrics.k8s.io", but that does
not have any meaning. This removes it for the readability.

* Trivial: Replace RC with RS for HPA doc

As RC doc[1], RS is now the recommended way to set up replication.
So this replaces RC with RS for HPA doc.
