go get github.com/zclconf/go-cty-yaml@v1.0.3

This includes the fix for a bug in what Terraform calls the "yamldecode"
function, where it was not correctly handling any situation where the
decode result is a null value. It was previously returning an unknown
value in that case, whereas now it returns a null value as expected.
