e2e tests docs need updating after repository move #702
Description
Files documenting the tests like e2e/README.md and e2e/DEVELOPING.md could use updating.
To highlight few main potential improvements:
- to also better align with (and be linked from) main trusity-ui readme,
- to explain possibly form of quick overview different types of tests implemented there (and why?) ... api, ui/features, ui/pages.
- ensure that npm commands are up to date and mention when execution is expected from trustify-ui directory (instead of from inside trustify-ui/e2e)
