📝 Clarify the list of supported TLS cipher suites

Previously, the documentation linked to Golang's source code, which
can drift from the list of cipher suites supported by Consul. Consul
has a hard-coded mapping of string values to Golang cipher suites, so
this is a more direct source of truth to help users understand which
string values are accepted in the `tls_cipher_suites` configuration
value.
