Added Lighthouse test GitHub action (alshedivat#2084)

Added support for Lighthouse test as a GitHub action, and it appears
like
[this](https://github.com/george-gca/multi-language-al-folio?tab=readme-ov-file#lighthouse-pagespeed-insights).
The only thing missing is for @alshedivat to create a [repository
secret](https://github.com/MyActionWay/lighthouse-badger-workflows#lighthouse-badger-easyyml)
named `LIGHTHOUSE_BADGER_TOKEN` with the information needed.
