In #33470 (and with a fixup in #34302) Foreman started to identify CentOS Stream as CentOS_Stream. However, this is creating problems in upgrades because the description and title have been taken.

What Foreman 3.1 creates:

 id | major |  name  | minor | nameindicator |         created_at         |         updated_at         | release_name |  type  |   description   | password_hash |      title      
----+-------+--------+-------+---------------+----------------------------+----------------------------+--------------+--------+-----------------+---------------+-----------------
  1 | 8     | CentOS |       |               | 2022-02-07 18:05:55.944924 | 2022-02-07 18:05:55.944924 |              | Redhat | CentOS Stream 8 | SHA256        | CentOS Stream 8

And Foreman Nightly:

foreman=# select * from  operatingsystems;
 id | major |     name      | minor | nameindicator |         created_at         |         updated_at         | release_name |  type  |   description   | password_hash |      title      
----+-------+---------------+-------+---------------+----------------------------+----------------------------+--------------+--------+-----------------+---------------+-----------------
  1 | 8     | CentOS_Stream |       |               | 2022-02-07 17:30:00.279439 | 2022-02-07 17:30:00.279439 |              | Redhat | CentOS Stream 8 | SHA256        | CentOS Stream 8

CentOS Linux 8 is End of Life and has been removed from the repositories. In order to minimize the risk for users it's safest to keep the name the same, especially now that Foreman 3.2 is about to branch. That means reverting the name change.

The various fact parser alignments should stay in.
