VSCode: Prepare for pioarduino transition (#10471)

Start reccomending the pioarduino VS Code extension instead of the PlatformIO extension.

pioarduino-based builds cannot complete correctly using the platformio extension. Normal platformio builds (nrf52, stm32) are unaffected//still work correctly.

Devs may need to delete their ~.platformio and .pio directories once after install in order to build properly.
