Currently our vscode repo is pretty lenient when it comes to linting. We don't do any checks in precommit or tests, which makes us rely solely on the assumption that the developer has installed the recommended vscode lint extension: https://github.com/mongodb-js/vscode/blob/master/.vscode/extensions.json#L5 and follows the lint suggestions it generates. This ticket involves adding a test to run a lint stage.

This test should fail if linting the code fails.

This ticket also involves fixing any lint errors which might come forward once we have this test activated.
