NIM. Docs for disconnected environments: need complete list of install options

Describe the bug

The list of install options for disconnected environments is not complete: https://docs.nginx.com/nginx-instance-manager/disconnected

• It should include Docker
  • Can be done in both a connected and disconnected environment

To reproduce

Additional context

From discussion:

So just to confirm, the customer can deploy in Docker by following the instructions in the 'connected' version of the documentation? Then to operate in 'disconnected' mode they can set the flag in the docker-compose.yaml file, so it looks like this:

Set the NIM license mode to connected or disconnected. Default is connected.

  NIM_LICENSE_MODE_OF_OPERATION: "disconnected"

Possible approach

Set up includes for near-identical content in both

• Disconnected environment
• Connected environment

Only difference: the flag noted in the discussion
