Chore: Replaces sass-lint with stylelint (#1413)

* Replaces `sass-lint` with `stylelint`

* Introduces standard scss rules from stylelint with only a few
  modifications.
* `yarn lint` now runs `yarn lint:style` instead of `yarn lint:sass`.
* Many of the files were updated with `yarn lint:style --fix`, but some
  of them had to be manually updated with overrides to adhere to the
  newly-introduced rules from the stylelint configuration.
* Includes a couple fixes such as fixing the class selector for
  `osdnSuggestionItem--value .osdSuggestionItem__text`.

Resolves #551

Resolves #1151
