doc: multi-hdd: refer to rebalance op (#1491)
The rebalance op links to the multi-hdd page, but the multi-hdd page does not refer to the rebalance op description and only states that an operator can launch a repair procedure without stating which procedure. Add a link to the rebalance repair procedure in the multi-hdd page to make it easier to find what procedure to run for rebalance. Reviewed-on: https://git.deuxfleurs.fr/Deuxfleurs/garage/pulls/1491
