Add support for yaml flow mapping and sequence (#94)

To test, copy package.json demo content to package.yaml editor

Before:


![20240511-043150](https://github.com/acao/codemirror-json-schema/assets/11596445/95bac852-61cd-4323-900f-ae866e0fdb6e)

It does not mark missing name and format errors in .contributors[0]

After:


![20240511-043212](https://github.com/acao/codemirror-json-schema/assets/11596445/b452aac1-8a84-49a9-952d-809c17b62a12)

Since yaml is a superset of json, I've also make all json validation
test cases to be run under yaml mode.
