Once T425625 concludes, reconfigure the linter tool to use the new repository as a source of rules:
- Connect the new ruleset repository to the linter tool without creating an NPM package (e.g., via repository loading in npm)
- Remove the ruleset from the linter tool and only use rules defined in the separate repository
- Clean up the linter tool repository so that it only contains the code related to its use as a web-based UI.
NOTE: Sized as if we do not need to account for versioning. If versioning is required, we will pause, rescope, and come back.
