examples/gnrc_border_router: esp_wifi_init failed with return value 257 on ESP32-C3 with nimble_rpble #19319
Description
Description
It is possible to do 6LoWPAN over BLE with nimble (see e.g tests/nimble_rpble_gnrc) so it makes sense to also use RIOT as a border router between WiFi and BLE with an ESP32.
While combining WiFi and BLE works fine on a classic ESP32, doing the same on ESP32-C3 fails to initialize the WiFi.
Steps to reproduce the issue

Expected results
Border router between WiFi and BLE (works on ESP32):
