Remove prefix of check ID in description

[roman-mueller]

Remove the prefix of the check ID in description.
All other descriptions do not contain the ID, this is the only one which is causing inconsistent output.

For example:

[PASS] 2.11  - Ensure that authorization for Docker client commands is enabled (Scored)
[PASS] 2.12  - 2.12 Ensure centralized and remote logging is configured (Scored) 
[PASS] 2.13  - Ensure live restore is enabled (Scored)

Thanks for the fix!
