Turn Repo Examples Into Living Tests

[alexfinnarn]

As discussed in #2, it is possible to move the code in examples to actual test files. The benefits of doing so include keeping test dependencies up-to-date and working together as well as making sure the advice in examples still works.

I will list out items in a checklist that can be turned into issues, so this can be considered an epic.

• [x] #4
• [x] #7
• [x] #5
• [x] Add axe-core and cypress-axe for accessibility testing
• [x] #9
• [x] #19
• [x] #21
• [x] Modify the main project readme file to explain how to run and learn from the tests.
• [x] Add to readme how to submit issues relating to Cypress from project work. The goal would be to help everyone using Cypress to know about new techniques/solutions that come up in project work.

The lists looks great. Looking forward to helping with this. We have working example of Cypress accessibility tests and github actions here https://github.com/CivicActions/accessibility that we can use.

Cool. I just made a PR and some issues linked to this epic. Have a look at those if you have some time, but I will pause now for some feedback.
