Announce that #7420 is fixed

This is part of a bigger issue https://github.com/Mbed-TLS/mbedtls/issues/7609
which is still pending since there are still configurations that are not
handled correctly. However https://github.com/Mbed-TLS/mbedtls/issues/7420
itself was fixed by https://github.com/Mbed-TLS/mbedtls/pull/7611.
