chore: fix README and dev/deploy.yaml

[tyler-lloyd]

• current readme link is a 404
• without the new doc indicator in dev/deploy.yaml, the manifest.yaml from the release doesn't separate the deployment and the synthesizer CRD so the synthesizer CRD isn't deployed when running kubectl apply -f "https://github.com/Azure/eno/releases/download/${TAG}/manifest.yaml"

example of synthesizer CRD missing when running the commands from the README
