regal: Update to 0.19.0

Changes:
0.19.0
------
This release adds several new options for setting configuration options
for rules in groups, allowing users to keep a static configuration
across updates, or to ignore certainly classes of rules. v0.19.0 also
includes a number of fixes to both linter rules and the language server
integration, making for an even better experience when using Regal from
VS Code or other LSP clients.

0.18.0
------
Only a week after v0.17.0, this release comes a little earlier than
planned as we found a few issues in the VS Code OPA extension
integration that we wanted to address as soon as possible. Nothing
serious, but having that extension provide a great Regal experience
feels important enough for us to warrant an earlier v0.18.0 release.
That's not all there is to this release though, as we have both a new
linter rule as well as a bunch of fixes included here. Enjoy!
