 *  Fix: Use the correct key size in the name of `TLS_AES_128_CCM_8_SHA256` which is a TLS 1.3
    cipher suite. We accidentally specified a key size of 256, preventing that cipher suite from
    being selected for any TLS handshakes. We didn't notice because this cipher suite isn't
    supported on Android, Java, or Conscrypt.

    We removed this cipher suite and `TLS_AES_128_CCM_SHA256` from the restricted, modern, and
