Section Number and Name:
3.1.1. Upgrading a Connected Satellite Server
3.1.2. Upgrading a Disconnected Satellite Server
3.3. Upgrading Capsule Servers (updated earlier in BZ 2096950)
6.1. Updating Satellite Server
6.2. Updating Disconnected Satellite Server
6.3. Updating Capsule Server

Describe the issue:
There is no need to enable the maintenance repository now as thats being handled by the satellite-maintain.

Suggestions for improvement:

Need to remove:

1. subscription-manager repos --enable \
   satellite-maintenance-6.12-for-rhel-8-x86_64-rpms
   and use below command for connected setup,

#satellite-maintain self-upgrade

And for disconnected setup,

satellite-maintain self-upgrade --maintenance-repo-label <6.12-maintenance-repo-label>

Additional information:
Earlier for 6.11, it was updated only for the capsule upgrade step, and other sections were missing in this https://bugzilla.redhat.com/show_bug.cgi?id=2096950 , so mentioned sections need an update for both 6.11 and 6.12 docs
