♻️ Add support for NEXTAUTH_URL_INTERNAL` option

[ghost]

• Update packages/dashboard/src/env/schema.mjs
• Add NEXTAUTH_URL_INTERNAL to the .env
• Update instructions and links appropriately.

This update will allow people to load the dashboard from the public IP and the internal IP. This way if they are hosting on their own machines they can have access it without having to use a different system on a different network.

With this there are two connection IPs. There is the public one accessible by others and the Internal IP only accessible from the host machine.

Both work perfectly with this update. Naturally though with this method if you want to access it form a seperate machine on the same network you will need to change the NEXTAUTH_URL_INTERNAL="http://0.0.0.0:3000" to NEXTAUTH_URL_INTERNAL="http://<private_ip>:3000" as localhost would not work for that.

For instance if your private IP was 192.168.0.29 the NEXTAUTH_URL_INTERNAL flag would need to be set to NEXTAUTH_URL_INTERNAL="http://192.168.0.29:3000"

Naturally you can see a description of this in the issue linked below:

• Add Support for NEXTAUTH_URL_INTERNAL flag in the .env file #749

Not loading it as intended. Will need to do some more tweaks before this is ready to be added.
