Subject: [PATCH] [CI] Enable Per PR Lighthouse CI Execution, Run nightly

lighthouse ci is still actively maintained and will be following a traditional release model. We should continue to use this package until it's functionality is replaced in playwright

* Add lighthouse to dependencies to track with dependabot

* Allow lighthouse to be triggered from PRs

* Update lighthouse.yml

* add lhci scrript

* bump to 16

* remove from deps until node 18

* document steps and add caching. Revert to 14

* ignore exit codes

* add secret for app

* remove env for baseline
