README issues after latest update

Link to "Steps to create Flux Manifest Repository" here https://community.opengroup.org/osdu/platform/deployment-and-operations/infra-azure-provisioning/-/blob/az/sa-fix-documentation/docs/flux.md is broken. In the same paragraph: "This step is optional and not recommended one for new installations" but next step with running common_prepare.sh fails because of

./infra/scripts/common_prepare.sh $(az account show --query id -otsv) $UNIQUE $PREFIX
ERROR: GIT_REPO not provided

and it looks like the previous step is needed. Or common_prepare.sh should be fixed.
