Revert shortcut change in block-deletion e2e test

[talldan]

This reverts commit ef01a14.

An e2e test that uses the block deletion shortcut was merged in #8961. Unfortunately the shortcut key was reverted back. This PR also reverts the shortcut used in the test.

Is this addressing wrongfully failed e2e tests?

[talldan]

@caxco93 not wrongfully failed - I reverted a change to a shortcut, but missed reverting it in a test in a different PR. This PR fixes.

I wonder why it wasn't failing in my PR with "shift" instead of "alt"

[talldan]

I think it gets picked up by our event handlers as just a standalone BACKSPACE.

[youknowriad]

I guess the difference, is we'll have an empty paragraph in one case and remove the paragraph in the other case? I wonder if there's a way to update the test to make it break with shift 🤷‍♂️

[talldan]

Yeah, I agree, that would be a good improvement. Making the test type some text before the backspace should have that effect.

I can push a commit that does that a bit later.

Hey @youknowriad - I've modified the test so that it'll fail now with the shortcut currently in master.
