Subject: [PATCH] Customize: Ensure the default message in `LockedNotification`
 is set to a string instead of `null`.

This avoids a JS error when passing the message to `wp.a11y.speak()` when showing the "changeset is locked" overlay to prevent two users from editing the same changeset simultaneously.

Props dlh.
Fixes #50500.
