web tutorials should be versioned

It'd be nice if the tutorials on the website were versioned. I'm still on 13.x so the configuration in these docs is incorrect for that version (and I learned it the hard way).

https://developer.hashicorp.com/consul/tutorials/security/tls-encryption-secure
https://developer.hashicorp.com/consul/tutorials/security-operations/tls-encryption-secure-existing-datacenter

It seems like the "documentation" is versioned, that is, this page:
https://developer.hashicorp.com/consul/docs

would be nice to have the same feature on the tutorials

Start by comparing the two linked TLS tutorial pages with the versioned Consul documentation landing page at https://developer.hashicorp.com/consul/docs. Determine how version selection works for the documentation and whether the tutorials can use the same mechanism. Done means the tutorials provide version-appropriate content, including the configuration relevant to Consul 13.x.
