Issue Description

Switching fromparserOptions.project: true toparserOptions.EXPERIMENTAL_useProjectService should in the worst case scenario should be roughly the same speed as before. The best case scenario should be faster. But checking it out on thegetsentry/sentry project, I'm seeing a raise from ~50s/65s to ~80s/110s. 😬

Baseline:

 $ time yarn lint:js                    yarn run v1.22.19$ eslint static/app tests/js --ext .js,.jsx,.ts,.tsx✨  Done in 49.47s.yarn lint:js  65.43s user 3.26s system 138% cpu 49.607 total

With the project service:

$ time yarn lint:jsyarn run v1.22.19$ eslint static/app tests/js --ext .js,.jsx,.ts,.tsx✨  Done in 81.42s.yarn lint:js  108.11s user 8.10s system 142% cpu 1:21.55 total
