[Internal]: CCS Permissions update #3866

Description

So if we apply permissions based on the doc here.

I can run into intermittent permission issues due to missing cluster:monitor/async_search/status

For example

action [cluster:monitor/async_search/status] is unauthorized for user [test_userapm-dev-ac] with effective roles [kb_usage,remote-search], this action is granted by the cluster privileges [monitor,manage,all]

This documentation should be updated to include this privilege so users can actually use Kibana for CCS without intermittent issues.
The documentation should also be updated to include only permissions actually used, as it currently has read_cross_cluster which doesn't seem to be necessary.
