The bundle is already in data/cert so nothing needs to be done but in case it needs to be updated, the ESP32 WifiClientSecure README and this were somewhat followed.
The x509_crt_bundle.bin file in data/cert was generated by downloading cacert.pem into the ./tools directory and then running
python gen_crt_bundle.py --input cacert.pem
mv x509_crt_bundle ../data/cert/x509_crt_bundle.bin
The gen_crt_bundle.py script comes from here
