Dart 2.19

[sourcegraph-wk]

Summary

This batch updates CI to use Dart 2.19. In most cases, updating Just Works™,
but here's some things that have changed or may cause problems while updating.

• The pub and dart2js aliases have been removed. You may need to replace bare pub commands. See the replacements here https://wiki.atl.workiva.net/display/CP/Dart+2.18+FAQ
• There may be some new lints, or lints that actually function better and now find new issues that need fixing or ignoring.
• Some lints may have been raised to warnings that now need fixing or ignoring until fixed.
• Dockerfiles or skynet may try to install things that don't work quite right on newer debian 11 (bullseye)
  • Potential examples are installing python or nodejs into the dart images
• If you have build.yaml files that "split" the builders into separate targets, you may have to exclude a new builder

    enabled: false
