[BUG] Build error in dwin.cpp

[CRCinAU]

@thinkyhead - I think this is what you've been working on lately?

Marlin/src/lcd/dwin/dwin.cpp:2389:1: error: expected identifier before 'void'
 void HMI_Temperature(void) {
 ^~~~
Marlin/src/lcd/dwin/dwin.cpp:2389:26: error: two or more data types in declaration of 'HMI_Temperature'
 void HMI_Temperature(void) {

Edit: On latest bugfix-2.0.x branch. I forget not everyone runs bugfix-2.0.x :)
