convert data/yaml to YAML-LD

[VladimirAlexiev]

I really like that you have data examples in YAML: https://github.com/3lbits/NoCIMExtensions/tree/main/data/yaml.
Could you please turn that to YAML-LD, so it's on par with https://github.com/3lbits/NoCIMExtensions/tree/main/data/jsonld?

• The YAML-LD spec is here: https://json-ld.github.io/yaml-ld/spec/
• Some YAML-LD tooling is here https://github.com/Accord-Project/yaml-ld-tools (but there are also many ways to convert YAML-JSON)

Hopefully, all you'd have to do is to:

• have the same keys in YAML as in JSONLD
• replicate the context

Then it will be a valid RDF serialization!
