Fix ui.quick_feedback() error in G26

[marciot]

Description

Fix for the following compilation errors due to missing TERN statements.

src/gcode/bedlevel/G26.cpp:329:12: error: ‘class MarlinUI’ has no member named ‘quick_feedback’
         ui.quick_feedback();
            ^
src/gcode/bedlevel/G26.cpp:346:8: error: ‘class MarlinUI’ has no member named ‘quick_feedback’
     ui.quick_feedback();
        ^

Would #25720 work instead?

Would #25720 work instead?

Yes, it would. I guess I will let @thinkyhead decide which fix is better. There already are some other instances of ui.quick_feedback() individually wrapped in TERN statements, so it seems like there are competing solutions to this particular problem.

The usage of quick_feedback (among other things) could use some rework generally. I would recommend separating concepts like the status message, audio feedback, etc. which are under the umbrella of MarlinUI into more granular concepts as we continue to modernize and clean up this elaborating codebase.
