Dokumentasjonsside for Docker uten desktop

### Description

Det finnes en dokumentasjonsside for oppsett av Docker uten Desktop for mac men ikke noe for windows, utenom denne tomme siden da: https://docs.altinn.studio/en/community/contributing/handbook/docker/without-docker-desktop/ Hadde vært fint med noe relevant innhold her.

### Additional Information

_No response_

Open the empty Windows page at the linked documentation URL and compare its structure with the existing macOS page for running Docker without Docker Desktop. Identify the Windows setup steps and prerequisites that should be documented, then verify that the page contains relevant, working guidance for contributors.
