regal: Update to 0.10.1

Changes:
0.10.1
------
This is a minor release to support the new setup-regal GitHub Action.
This release improves the --format github output so that it no longer
only reports violations in the form of annotations in the PR, but also
prints the --format pretty table to the actions console, allowing you
to quickly identify issues in either of the views.

As an added bonus, this release also features new documentation for the
aggregate rule rule type introduced in v0.10.0, so that custom rule
authors now may try them out.
