Added a new package containing playwright rulesets
it exposes regular and requiring-type-checking variants which derive from the base typescript ruleset
it adds configurations for rules as discussed in #114
updated root README to mention it and describe its configuration
Added smoke tests for the package. I initialized these using Playwright's setup instructions then deleted a bunch of unnecessary stuff since we don't actually execute the Playwright test.
I noticed that the npm run lint command was failing on existing code so I fixed violations (just whitespace) and enabled it in the pipeline.
Justification
Fixes #114.
Implementation
npm run lint
command was failing on existing code so I fixed violations (just whitespace) and enabled it in the pipeline.
