Fix specification for cluster.remote.connect (#48690)
Fix specification for cluster.remote.connect (#48690)

The docs specify that cluster.remote.connect disables cross-cluster
search. This is correct, but not fully accurate as it disables any
functionality that relies on remote cluster connections: cross-cluster
search, remote data feeds, and cross-cluster replication. This commit
updates the docs to reflect this.
