Incorrect behaviour of "dev --country" command

[MarcL]

Describe the bug

When using ntl dev --country=<2-letter-iso-code> it fails to set geo=mock as suggested in the documentation.

country (string) - Two-letter country code (ISO 3166-1 alpha-2, https://en.wikipedia.org/wiki/ISO_3166-1_alpha-2#Officially_assigned_code_elements) to use as mock geolocation (enables --geo=mock automatically)

Instead it reads the cached or real version of the country code if it exists.

Steps to reproduce

This was reproduced with the Astro starter kit.

1. Clone the repository git clone git@github.com:sarahetter/astro-netlify-edge-starter.git
2. Install dependencies: npm install

Incorrect behaviour

1. Start the dev server using ntl dev --country=AU to choose Australia as the country code
2. Observe the page at http://localhost:8888 - the message displayed will be "Welcome, visitor from United Kingdom!" (this will be shown as your own country name instead of "United Kingdom")
3. This is incorrect behaviour as the geolocation has not been mocked with the Australia country code
4. Using console.log(context); to log the edge function context shows my UK-based geolocation:

  geo: {
    city: "Warrington",
    country: { code: "GB", name: "United Kingdom" },
    subdivision: { code: "ENG", name: "England" }
  }

Correct behaviour by adding the geo command

1. Start the dev server using ntl dev --country=AU --geo=mock to choose Australia as the country code AND to enable geolocation mocking
2. Observe the page at http://localhost:8888 - the message displayed will be "Welcome, visitor from Mock Country!"
3. Using console.log(context); to log the edge function context now shows:

  geo: {
    city: "Mock City",
    country: { code: "AU", name: "Mock Country" },
    subdivision: { code: "SD", name: "Mock Subdivision" }
  }
