[Bug]: Infinite `init_hook` execution if `devbox services start` is called

[mikenikles]

Current Behavior (bug)
If I call devbox services start within the init_hook array of commands, the shell never starts and instead ends up in an infinite loop.

Expected Behavior (fix)
The shell starts and services are up and running.

Additional context
devbox version -v

devbox version -v

{
  "packages": [],
  "shell": {
    "init_hook": [
      "echo 'This comes from the init_hook.'",
      "devbox services start"
    ],
    "scripts": {
      "test": [
        "echo \"Error: no test specified\" && exit 1"
      ]
    }
  }
}

@mikenikles thanks for reporting!

@mikeland73 I think this is a result of the change to start a new "devbox shell" environment with each devbox services start. We may need some recursion protection.
