Description

This should be done after #1047

Currently the locators in the e2e tests use mostly ids and class names to locate elements. This should be changed to use accessibility locators as that is how our flesh-and-blood human users will locate elements in real life.

Some of the components themselves will need to be made more accessible for this to work, so this should be done in pieces with multiple PRs to keep the changes from getting too large.
