fix: multiline for yaml on share

The following patch fixes a bug discovered on yaml marshalling when
handling multiline input. Essentially, when pushing to an OCI artifact
to an OCI complaint registry, the yaml for multiline indentation is
removed. Causing issues with marshalling the yaml for usage.

Tested the change by working locally and sharing to an OCI registry
for comparison.
