Section Number and Name: 2.2. Prerequisites and 2.3 Pulp Data Considerations

Describe the issue: 

Please update this section:

"""
A backup from Satellite versions 6.1, 6.2, or 6.3 that you make using the katello-backup script. You can use a backup with or without Pulp data. 
"""

to:

"""
A backup from Satellite versions 6.4 or later that you make using "foreman-maintain backup" script. You can use a backup with or without Pulp data. 
"""

Also, katello-backup is referenced lower:

"""
 katello-backup --skip-pulp-content /var/backup --assumeyes
"""

should be replaced with:


"""
 foreman-maintain backup online -y --skip-pulp-content  /var/backup/
"""


as well as:

"""
 katello-backup /var/backup --assumeyes
"""

to:

"""
 foreman-maintain backup offline -y /var/backup/
"""
