helix: Stay in helix normal mode after helix delete (#34093)

Currently, the HelixDelete action switches to (vim) Normal mode instead
of HelixNormal mode. This adds a line to the helix delete action to stay
in helix normal mode.

There was already a commented-out test for this. I've uncommented it and
it now passes.

Release Notes:

- helix: Fixed switching to vim NORMAL mode instead of HELIX_NORMAL mode
after deletion
