Issue in /src/pages/guides/getting-started/permissions.md

Clarify permissions necessary for content copy (i.e. operations related to content flow and content set). According to https://experienceleague.adobe.com/docs/experience-manager-cloud-manager/content/using/content-copy.html?lang=en#permissions this seems to require the "Deployment Manager" role.

For AEMaaCS additional permissions are needed: https://experienceleague.adobe.com/docs/experience-manager-cloud-service/content/implementing/developer-tools/content-copy.html?lang=en#permissions. It is unclear though how to assign those permissions to a JWT service user or OAuth service user described in https://developer.adobe.com/developer-console/docs/guides/authentication/ServerToServerAuthentication/.
