This adds a new workflow `update_kittest_snapshots.yml` that can be
triggered through the [kitdiff](https://github.com/rerun-io/kitdiff) ui
when viewing a ci artefact.
Also adds a link to kitdiff to view the pr changes to each commit (via
the preview build comment)

It seems like the thresholds are too low for all tests to pass when
snapshots are generated from windows / linux. We need a better solution
to this problem, but in the meantime this script should allow
contributors to update their snapshots by downloading them from the last
CI run.
