Fix markdownlint in site (nginx#1499)

Problem: The configuration for the `site` directory didn't have a
standard name and wasn't getting picked up by markdownlint-cli. The
Makefile was also referencing .markdownlint.yaml that doesn't exist.

Also the configuration for .pre-commit-config.yaml was invalid and the
autoupdate wasn't working correctly.

Solution: Change the name of the configuration to a standard one that
can be used automatically be the tool.
Update pre-commit config and Makefile and run the linter to fix the
existing problems.

 1. We create a gateway resource for our domain (cafe.example.com) and configure cert-manager integration using an annotation.
 1. This starts the certificate issuance process – cert-manager contacts Let’s Encrypt to obtain a certificate, and Let’s Encrypt starts the ACME challenge. As part of this challenge, cert-manager creates a temporary HTTPRoute resource which directs the traffic through NGINX Gateway Fabric to verify we control the domain name in the certificate request.
 1. Once the domain has been verified, the certificate is issued. Cert-manager stores the keypair in a Kubernetes secret that is referenced by the gateway resource. As a result, NGINX is configured to terminate HTTPS traffic from clients using this signed keypair.
-1. We deploy our application and our HTTPRoute which defines our routing rules. The routing rules defined configure NGINX to direct requests to https://cafe.example.com/coffee to our coffee-app application, and to use the HTTPS listener defined in our gateway resource.
