This bumps user-event library by a major release and resolves the breaking changes.
Direct invocation of `userEvent` APIs (such as `userEvent.click()`and `userEvent.type()`) was replaced by calling the methods returned by `userEvent.setup()` as described here:
https://testing-library.com/docs/user-event/intro
'ami' was deprecated a while ago, and is kept around as an alias of
'aws'. Same with 'vhd' and 'azure', and 'vhd' and 'gcp'.
This maintains support for the old aliases where necessary.
