Add an (expired) root cert,
DST Root CA X3
, to the roots cert list to handle the special way Let's Encrypt does its root cert. See details here: adafruit/certificates#1.This cert was present in the older NINA-FW list. It was removed when the roots cert bundle was completely reworked in #8374. But mbedTLS does not seem to work properly with the Let's Encrypt scheme without this cert.
