[Bug]: Unable to edit project configuration after initialization, `deno.json` not read

### Problem description

After linking a Git repository for automatic deployment, which provides a UI for project configuration, there is no way to change that configuration without unlinking and relinking the Git repository to reset the process.

### Steps to reproduce

Create and link a project. Try to find configuration settings. Not present.

### Expected behavior

Some way to edit project configurations. See suggestions below.

### Environment

_No response_

### Possible solution

There should be a tab for project configuration, and/or Deploy should actually read the `deno.json` configuration - I would prefer to only have to edit a file in source control and have my automatic deployments respect that configuration instead of having to do it through the UI everytime.

### Additional context
