hi there, when i try to run

zed validate

against the example YAML provided in https://authzed.com/docs/spicedb/modeling/validation-testing-debugging#zed-validate, i get the following error:

➜  scratch zed validate test.yaml 
8:39AM ERR terminated with errors error="error parsing relationship `object:foo#relation@subject:bar object:baz#relation@subject:qux`: invalid relationship string"

does anyone know what i'm doing wrong? thanks!
