Document test procedure for Project Page

### Dependency
- #6412

### Overview
We need to document the test/review process for ensuring that the various elements of the Projects Page are still working after a change.

### Action Items
- [ ] We are currently in the process of moving the old wiki to the new [website-wiki repo](https://github.com/hackforla/website-wiki), so we will not be making any changes or additions to the old wiki at this time. Thus, we will be adding wiki content through a different process now. Read [How to Contribute to the Wiki](https://github.com/hackforla/website/wiki/How-to-Contribute-to-the-Wiki). Follow the process given in [How to Contribute to the Wiki](https://github.com/hackforla/website/wiki/How-to-Contribute-to-the-Wiki) when completing the remaining Action Items.
- [ ] Create list of items that should work - see the wiki page [^1]
- [ ] Create a list of steps for replicating how each is working (add under resources sublist below)
- [ ] Get signoff from dev and product leads
