language_settings: Add `auto` alias for subtle edit prediction mode (#25686)

Marshall Bowers created 10 months ago

This PR makes `auto` an alias for the `subtle` edit prediction mode.

Right now I'm in a state where I can't have valid settings in both
development and Nightly because the settings values are disparate.

Release Notes:

- N/A
