Document how extra Flux controller replicas behave - #2709

Extra replicas don't add capacity because only the leader reconciles, and extra source-controller replicas never become ready, so the rollout never completes. Say so on the sharding page and point to sharding instead. Signed-off-by: Luca Marsella <34103646+marsluca@users.noreply.github.com>

Extra replicas work for failover, they just don't add capacity. Standby source-controller replicas stay not ready by design. Signed-off-by: Luca Marsella <34103646+marsluca@users.noreply.github.com>

Fixes fluxcd/flux2#5880
Adds a note to the sharding page about extra controller replicas, as discussed in the issue. They work as failover standbys but don't add capacity, since only the leader reconciles. Standby source-controller replicas stay not ready by design. The note points to sharding for spreading the load.
I built the site with Hugo 0.122.0 and checked that the note renders on the page.
