Fix "Show Edit Predictions For This Buffer" button (#50845)

Closes #48393

When switching the language of an unsaved buffer (e.g., from Plain Text
to JavaScript), the editor's edit_prediction_settings were not
recalculated. This caused the "This Buffer" toggle in the edit
prediction menu to show a stale state, making the first click a no-op. I
added a call to update_edit_prediction_settings in the LanguageChanged
event handler so the editor immediately reflects the correct edit
prediction state for the new language.

- Fixed the "Show Edit Predictions For This Buffer" toggle being a no-op
in unsaved buffers after switching the buffer's language.
