fix(ci): Clean up package.json for linting and release

The `package.json` configurations for commitlint and semantic-release
can be pruned:

* Remove `commitlint` overrides for line length. This was to fix a bad
  commit added upstream.

* Stop supplying `plugins` for "release." Doing so overwrites
  configuration done in the main config and can cause unintended
  consequences. We have changed our tooling to allow everything to be
  defaulted, and provide only the name of the correct changelog.
