variable DEFAULT_MAX_VERSION
The default value of the maxVersion option of createSecureContext().
It can be assigned any of the supported TLS protocol versions,
'TLSv1.3', 'TLSv1.2', 'TLSv1.1', or 'TLSv1'. Default: 'TLSv1.3', unless
changed using CLI options. Using --tls-max-v1.2 sets the default to 'TLSv1.2'. Using
