Remove localization for debug-only Wormholy string

[mokagio]

Following up on this comment by @jaclync

Description

We should the debug menu entry to toggle Wormholy only in non-public-facing builds. Therefore, we can avoid sending the UI string for localization and save the effort there.

Granted, once the string is localized, there is basically no overhead in having it in the code. Still, from a tidiness point of view, it's neat to remove it.

Testing information

Launch the app on device and verify the menu reads as expected:

• I have considered if this change warrants user-facing release notes and have added them to RELEASE-NOTES.txt if necessary.

The next time a release runs, we should expect all the "Launch Wormholy Debug" entries in the localization files to be removed.
