Update ESP32 BSP to 2.0.0 latest

[brentru]

Currently, we're building on arduino-esp32 2.0.0-alpha.1 forTinyUSB support. TinyUSB was updated recently to add support for ESP32-S2 arduino core version 2.0.0 (adafruit/Adafruit_TinyUSB_Arduino#126).

We should merge this into WipperSnapper master and update the build-esp32s2 CI workflow (https://github.com/adafruit/Adafruit_Wippersnapper_Arduino/blob/master/.github/workflows/release.yml#L31) to remove manually fetching the Adafruit branch add-tinyusb, build from latest instead.
