chore: update the output of the slack stats

This updates the Jenkins output for slack to show both overall AC coverage stats and the current milestone stats.

The intended output is like this:

All ACs:
Criteria: 2386  Covered: 1790  by/FeatTest: 565  by/SysTest: 1160  Uncovered: 596  Coverage: 75.0%
Current milestone ACs:
Criteria: 100  Covered: 99  by/FeatTest: 98  by/SysTest: 1  Uncovered: 1  Coverage: 99.0%
