chore(crashtracking): add python version to crashtracker tags [backpo…

…rt 2.13] (#10733)

Backport fe5b42f from #10720 to 2.13.

During escalations it's currently difficult to find the exact Python
version relevant for a defect. This is a simple fix for that.

I'm recommending a backport because
1. The fix is simple
2. 2.11 and onward introduce crashtracker, and we're still dealing with
crashes from those versions
