Generate expo-updates private key, public key, and code signing certificate using that public key (self-signed by the private key)

{bold Usage}
  {dim $} npx expo-updates codesigning:generate --key-output-directory <dir> --certificate-output-directory <dir> --certificate-validity-duration-years <num years> --certificate-common-name <name>

  Options
  --key-output-directory <string>                  Directory in which to put the generated private and public keys
  --certificate-output-directory <string>          Directory in which to put the generated certificate
  --certificate-validity-duration-years <number>   Certificate validity duration in years (number of years before certificate needs rotation)
  --certificate-common-name <string>               Common name attribute for certificate (generally the human readable name of the organization owning this application)
  -h, --help                                       Output usage information
