man scap-security-guide(8) mix Centos and RHEL

#### Description of problem:

```man 'scap-security-guide(8)'```
lists profiles, first profile is named:
```
...
Profiles in Guide to the Secure Configuration of Red Hat Enterprise Linux 7
Source Datastream: ssg-centos7-ds.xml
...
```
It is definitely not about 'Red Hat Enterprise Linux 7' but 'CentOS 7'. It is not good to mix and match trademarks. RHEL has a actual sections later in manual and it has much more profiles.

#### SCAP Security Guide Version:

scap-security-guide-0.1.60-1.fc35.noarch

I see this also with master 49a3e57f74b68c1cb8c46f1583c3ef141daa5ea4, but I don't have clean build to show. Artifacts below is generated by above versions.

#### Operating System Version:
