curl(1) TLS version 1.3 missing from --tlsv1 description

[andreaso]

The curl(1) man page has the following to say about the --tlsv1 option.

(SSL) Tells curl to use TLS version 1.x when negotiating with a remote TLS server. That means TLS version 1.0, 1.1 or 1.2.

Shouldn't that description also mention version 1.3? Something like the following.

(SSL) Tells curl to use TLS version 1.x when negotiating with a remote TLS server. That means TLS version 1.0, 1.1, 1.2 or 1.3.

That's because so far libcurl doesn't do TLS 1.3 by default, only when you explicitly ask for it. But I think that's more because we haven't remembered to change that since back when we added it with a bit of precaution... I'll file a PR to change this! (both docs and code)
