Instead output a warning about it and continue with the defaults.

These SSL versions are typically not supported by the TLS libraries since a
long time back already since they are inherently insecure and broken. Asking
for them to be used will just cause an error to be returned slightly later.

In the unlikely event that a user's TLS library actually still supports these
protocol versions, this change might make the request a little less insecure.
