SLES 15.7 uses chronyd instead of ntpd - role fails

[nikolaisen-hhpv]

We're calling this ansible role from another playbook. In SLES 15.7 machines it fails:

TASK [geerlingguy.ntp : Ensure NTP package is installed.] **********************
[ERROR]: Task failed: Module failed: No provider of '+ntp' found.

     ^ column 3

We need to distinguish between SLES <= 15 and SLES >= 15.
