ESP WROOM 02 board name hard to find

[ToMe25]

Currently the name for the ESP8266 wroom 02 board is ESP-WROOM-02, while all the other espressif boards have Espressif at the start of their name.

This made me take pretty long to initially find it.

I recommend changing the name from ESP-WROOM-02 to Espressif ESP8266 Wroom-02 to make it easier to find.
