Update Code to 1.94.2 (#7026)

* Update Code to 1.94.2

* Convert from yarn to npm

This is to match VS Code.  We were already partially using npm for the
releases so this is some nice alignment.

* Update caniuse-lite

This was complaining on every unit test.

* Update eslint

I was having a bunch of dependency conflicts and eslint seemed to be the
culprit so I just removed it and set it up again, since it seems things
have changed quite a bit.

* Update test dependencies

I was getting oom when running the unit tests...updating seems to work.

* Remove package.json `scripts` property in release

The new pre-install script was being included, which is dev-only.

This was always the intent; did not realize jq's merge was recursive.

* Remove jest and devDependencies in release as well

* Update test extension dependencies

This appears to be conflicting with the root dependencies.

* Fix playwright exec

npm does not let you run binaries like yarn does, as far as I know.

* Fix import of server-main.js

* Fix several tests by waiting for selectors
