Demo Mode: The "Purchase Now!" link's destination is incorrect

The bug

When the "Purchase Now!" CTA is clicked in the Demo Mode introduction popup, the following URL is opened: http://www.minecraft.net/store?source=demo. This appears to be sensible, but it simply redirects to https://www.minecraft.net/en-us?source=demo. It is possible that the store link was changed and the Purchase Now link was not updated.

To reproduce

1. Run the game in Demo mode. (You can do this manually by specifying the correct arguments to the client.jar or you can select a Mojang account that has not brought the game in the Launcher.)

2. Click "Play Demo World" to generate/enter the demo world.

3. When the Demo Mode introduction popup appears, click the "Purchase Now" button on the left.

Observed behaviour

The user ends up at the Minecraft.net homepage

Expected behaviour

The user would be taken to somewhere like https://www.minecraft.net/en-us/store/minecraft-java-edition or https://www.minecraft.net/en-us/store/loot.jsp
