Description of problem:
For inActive rules, we are showing Alert State as `Not Firing` which considered confusing because it looked like it represented an additional alert state.
Steps to Reproduce:
1. Navigate to Monitoring Alerts tab
2. In the Alert State column see the Not Firing for inactive rules.
Not Firing Alert State has been shown for inactive rules.
Alert State should be - for inActive Alert State.
Reproducibility (Always/Intermittent/Only Once):
