Fix stylelint packages

[TylerJang27]

The stylelint config was referencing a package that wasn't being installed.

Also upgrades the CLI.

In the Stylelint config, I see the following:

  - stylelint-config-standard-scss
  - stylelint-config-prettier
  - stylelint-config-clean-order

I think we need all of these packages (none are installed by default by Stylelint)?

My guess is it only erred on the first one it looked for

Also, it seems that stylelint-config-prettier is incompatible with Stylelint >= 15.x, and the package has been deprecated. I propose we just nix it from the default config (which is separate from this PR, but also semi-related because this PR deals with packages from our default config)

[TylerJang27]

I modified the stylelint config and extra packages to be correct (fixed) and also renamed the config to the js version, which is a "lower priority" as far as stylelint is concerned, allowing us to override it more easily, and allowing the collision to be detected in the marketing repo.

@drwpow. This is ready for re-review when you get the chance

Looks great! 💯

Also thanks for the ping—I missed the earlier update (sorry!)
