[SOLR-11634] Create collection doesn't respect `maxShardsPerNode`

Description

Command

curl 'http://host:8983/solr/admin/collections?action=CREATE&name=xxx&numShards=16&replicationFactor=3&collection.configName=config&maxShardsPerNode=2&rule=shard:*,replica:<2,node:*&rule=shard:*,replica:<2,sysprop.aws.az:*'

creates collection with 1,2 and 3 shard per nodes - looks like maxShardsPerNode is being ignored.

Adding rule=replica:<{},node:* seems to help, but I'm not sure if this is correct and it doesn't seem to match documented behaviour.
