Bump karma and dependencies

[zzak]

My only question is how does the global yarn.lock file get updated?
https://github.com/rails/rails/blob/main/yarn.lock

There is also a problem with karma-sauce-launcher with 4.0.0 that we will want to avoid specifically:
karma-runner/karma-sauce-launcher#190

My only question is how does the global yarn.lock file get updated?

Maybe this?

yarn upgrade karma-sauce-launcher@^4.3.6

[zzak]

yarn upgrade karma-sauce-launcher@^4.3.6

This adds a huge diff to the root yarn.lock file, and adds karma-sauce-launcher to the root package.json dependencies.

From the CI config, it seems we run yarn install from the root, and npm install from the actionview directory.

There doesn't seem to be any documentation for how this file is maintained that I could find. 🤔

I think a yarn install would update the lockfile?

and npm install from the actionview directory.

This definitely seems wrong, we should probably be using yarn everywhere.

We do except actionview (at least in CI) for whatever reason:

Will update the PR with yarn install run from the root 🙏
