Document the ESP32-H4 toolchain requirement.

Add that ESP32-H4 requires idf.py --preview set-target esp32h4 and that chip revision v0.2 requires ESP-IDF master. Without this note, users can follow the support list with an incompatible stable IDF and fail before building the example. (github.com)

Review comment at @port/dwc2/README.md at line 39:
Update the ESP32 chip support list in the README to document that ESP32-H4
requires `idf.py --preview set-target esp32h4`, and that chip revision v0.2
requires ESP-IDF master.

After applying the fix, consider running `coderabbit review --agent` for local
