show custom domain on `spin deploy`

[bacongobbler]

I have an application deployed to Fermyon Cloud with a custom domain:

When I call spin deploy, I see the default fermyon.app domain URL.

><> spin deploy
Uploading spin-hello-world version 1.0.0-rc3fe1b7e to Fermyon Cloud...
Deploying...
Waiting for application to become ready........ ready
Available Routes:
  hello: https://spin-hello-world-bacongobbler2.fermyon.app/hello
    A simple component that returns hello.

The expected behaviour should be to see the custom domain:

><> spin deploy
Uploading spin-hello-world version 1.0.0-rc3fe1b7e to Fermyon Cloud...
Deploying...
Waiting for application to become ready........ ready
Available Routes:
  hello: https://helloworld.bacongobbler.com/hello
    A simple component that returns hello.
