Expose deploy preview URL in ENV

[laem]

What problem will this feature address?

My bun/Next application needs the URL of the deployment to work properly. I'm passing the URL from the build script to the client.

On the following capture, the 9uf1rf looks like a random key that is not discoverable.

Describe the solution you'd like

I'd like to have access to a DOKPLOY_DEPLOY_URL variable in my bun run build script.

Describe alternatives you've considered

Not using the preview deployment feature :/
