ssh: Use system prompt for the server removal action (#19332)

This PR replaces a toast for the system prompt to confirm the action of
removing a server from the remote list. The alert dialog component is
the right choice here as we want to have a modal action that forces
choice. This should make it easier to convert to a nativa alert dialog
in the future, as well as for other platforms.
