Check if we parse yamls correctly

Description

This is likely an error with old CLI, but we should check if we have the same issue with modulectl.

Telemetry created a ModuleTempalte where default CR starts with ---, see: https://github.tools.sap/kyma/module-manifests/blob/9012a3d1325e1f21dc8a0fcf94b903bb35fc9e3f/modules/telemetry/experimental/telemetry-default-cr.yaml#L1

Expected result

ModuleTemplate shall not have yaml separators ---

Actual result

ModuleTemplate has yaml separators ---

Steps to reproduce

Troubleshooting

instead of copy and paste of the input data you could do something like
yq -n '.spec.data=load(.telemetry-default-cr.yaml)'
