Fixes the issues where using the zed builtin prompt when removing
wsl/ssh remote servers did not capture focus and caused input to be
passed to the existing picker/editor.

Closes #60840.

# Objective

The objective of this fix was to make the remote server removal prompts
work correctly, capture focus, when using keyboard navigation to remove
a server or wsl distro. The fix was created directly to address #60840.

## Solution

The solution here is quite simple, we remove the forced, focus lines,
that attempt for the context to capture the new prompt window. The
oringal additional call to `cx.focus` was entirely unnecessary and was
duplicated from the original ssh remote server addition, into the wsl
distro addition. This behaviour and the correct deferal is handled by
the receivers invocation upon the execution of the listitem.

## Testing

I tested these changes manually, however this is incredibly easy to
reproduce, and is entirely platform agnostic. Simply add a testing
distro to the list, and then attempt to remove that distro by going into
its settings and removing the sever/distro. Then use the keybinds to
attempt to navigate. Prior to this PR, this would cause you to interact
with the editor behind the prompt, but now correclty directs
actions/inputs to the prompt window.
