libressl TLS 1.3 feature request

[Nam Nguyen]

Can TLS 1.3 be enabled for libressl? I tested the latest wget 1.21.3 on
OpenBSD and wanted to test "Add option to select TLS 1.3 on the command
line."

According to this, TLS 1.3 support should be ready. related:

Your OpenSSL version is too old to support TLS 1.3
Disabling SSL due to encountered errors.
