Implement a workflow to comment any diffs in a PR comment to the lighthouse score of the site

[NabbeunNabi]

Problem

We would like to maintain as high of a lighthouse score as possible, so need to make sure that new PRs do not introduce things that are detrimental to our google lighthouse score. We also want to encourage practices that improve our lighthouse scores and know when a PR improves our score

Success

A comment is generated in a PR that shows any differences in a PR between our current lighthouse score versus our past lighthouse score using GitHub actions.

Requirements

• Add a workflow that generates a PR comment after comparing the lighthouse score of our live website versus the PR lighthouse score.
• Explain in the PR how it works with a clear explanation and screenshots

Implementation notes

The file where the workflows are held are here. There is one already that can get the lighthouse scores. You can either build a new one or add it to the existing one.
