Short term bodge for PRODUCT warning

[zvecr]

Description

With code freeze looming, virtually every keyboard is spitting out the following warning

make zvecr/zv48:default:flash
QMK Firmware 0.14.31
⚠ zvecr/zv48/f401: PRODUCT in config.h is overwriting keyboard_name in info.json
Making zvecr/zv48/f401 with keymap default and target flash

⚠ zvecr/zv48/f401: PRODUCT in config.h is overwriting keyboard_name in info.json
arm-none-eabi-gcc (Arch Repository) 11.2.0

While maybe a better experience while porting new keyboards, this is just going to cause issues for the majority. (Just look at how many questions get raised about the arm size warning)
