[Findit] Flake Analyzer - Fixing auto revert commit body

1. Use the MasterFlakeAnalysis' original build number when pointing to
   a sample failed build.
2. Remove footer, as the information in there is already provided in the
   body of the revert text
3. Update flake analysis text to say "Flaky Test" instead of "Failed test"
