Improving Automated Accessibility Checks

[garyb1]

I think we could do a number of things to improve a11y in the codu codebase.
Some suggestions are:

1. Adding automated checks to Github actions. See how canaxess implemented automating accessibility testing.
2. Add Eslint jsx a11y to our eslint plugins
3. Add jest-axe to any unit tests being carried out. This also uses axe-core behind the scenes.
4. Ensure all PR's have meaningful alt text with the Github alt text bot.

This was a fantastic addition! Thanks @garyb1

@NiallJoeMaher no problem! 🙂 I didn't get to do step 1 but can always create another issue for that

My bad! Lets keep it open until then in case someone wants to pick it up.
