Link to places of the guide in the CLI

In places of the CLI, most notably thrown UserErrors and commands that have a post step the user has to do manually, we should link a resource on the docs.

https://disploy.dev/docs/Guide/learning-the-workflow/deploying#configuring-environment-variables and https://github.com/Disploy/disploy/blob/22b8781a3d9b0739d9e3fadbb8820ce999ae8225/apps/cli/src/commands/deploy.ts#L37

We should probably also setup redirects so the links aren’t so long, example disploy.dev/cf-vars
