under the section - enbling stream-based retention with Loki
the following warning exists:

"This is not for managing the retention for stored logs. Global retention periods for stored logs to a supported maximum of 30 days is configured with your object storage." 

this explains what we are NOT configuring, but it does not actually explain what we ARE configuring - if its not "stored logs" then clearly say what is being controlled by this retention setting 

the warning could also be update to say: 

"This is not for managing the retention for stored logs. Global retention periods for stored logs to a supported maximum of 30 days is configured within your s3 compatible object storage providers configuration." 

making it clear that this needs to be configured outside of the operator config.
