README has the wrong link for Enterprise Consul

[cpustejovsky]

Overview of the Issue

The current link https://developer.hashicorp.com/docs/enterprise to a 404 page.

Based on my Google search, this link was appropriate.

https://developer.hashicorp.com/consul/docs/enterprise

Reproduction Steps

1. Go to https://github.com/hashicorp/consul/blob/main/README.md
2. Click on the Consul Enterprise link before the Quick Start section

Recommended Fix

I believe the correct link is https://developer.hashicorp.com/consul/docs/enterprise

I have created a PR #22386 to fix this.
