Update Vale CI action to handle large diffs

This PR helps us to avoid running into the issue described in
reviewdog/reviewdog#1696, where diffs that
are too large will cause Vale to fail

The diff between the versions of Vale and the new one can be viewed
[here](https://github.com/errata-ai/vale-action/compare/c99f2d..91ac40).
Since they also allow you to specify which version of reviewdog to use,
we'll use the most recent one which includes all the changes made so far
that are supposed to fix the issue with large diffs.
