When using Completions UI such as Vertico or Helm, there is no way to
exit from Keyword Section to go to next auto-insert Sections unless the
user press a key sequense, for auto-insert input a empty string allow
close Keyword section without cancelling the next auto-insert actions.

This can be more a problem with `completing-read' than Completions UI,
that is why setting an empty string as default value fix this and can
fix this similar issue to other completions packages.
