Install a github action to run Lighthouse on PR

[SallyMcGrath]

I want to do this:

Install a github action to run Lighthouse on PR These are the coursework repos: https://github.com/CodeYourFuture/Table-of-Contents These are the template repos: https://github.com/CodeYourFuture/CYF-Coursework-Template

Given a coursework repo When a trainee opens a pull request And the coursework contains or produces complete HTML pages Then Lighthouse is run And the score is reported on the pull request

When the score is less than 100 on Accessibility Then the PR is set to draft

Here’s why I want to do it:

We have found that Lighthouse is really helpful for helping trainees evaluate their own code Setting a lighthouse report on PR is useful for trainees and volunteers to check basic front end quality

Here’s how it serves our goals:

• automation frees up volunteers for meaningful technical mentorship
• we want trainees to write good code and this will help them and help them see how to fix things
• Also listed on Syllabus https://github.com/CodeYourFuture/syllabus/issues/529

This is how much time I can put towards this change:

• I can spend 3 hours over 4 weeks testing this for a devops person and merging it in to relevant repos, but I cannot teach someone to do this and then test it for them -- I need devops people to take this forward as I don't have capacity

This is the help I need from others to get this done (if any):

• a devops grad or volunteer to put this in place
• @Dedekind561 to keep an eye on how it will work with his github actions
