feat(decl/loader): replace go-yaml/yaml with goccy/go-yaml
Browse files Browse the repository at this point in the history 
Replace go-yaml/yaml as it is practically not maintained anymore
and requires additional code to be written for marshalling
structures specifying 'inline' on any on their fields.
