Add TLSv1.3 to SslProtocol list

[mungojam]

It seems the list here is limiting what can be set for the terraform AWS provider for cloudfront vpc origins:

aws-sdk-go-v2/service/cloudfront/types/enums.go

Lines 936 to 943 in 2704503

	func (SslProtocol) Values() []SslProtocol {
	return []SslProtocol{
	"SSLv3",
	"TLSv1",
	"TLSv1.1",
	"TLSv1.2",
	}
	}

I don't know how this list is used, but is it logical to add TLSv1.3 to this list since it is supported in most/all AWS components now?
