[V8] Change waterfall bot to skia rolls

This changes the code-review query to fetch roll data matching the
Skia auto roller. The options are changed to now include the full
commit message in the output data. Full query [1].

The V8 version is now extracted from the message, where it appears
as the first item of the log (also in patched rolls).
Example roll: [2].
