Csaba Osztrogonác 00f682e746 tools: enforce restriction on YAML negative key
The phase field must precede the type field for negative tests
to have a consistent style and be able to parse easier.
Related to the goal of https://github.com/tc39/test262/issues/1997

Added this check to the linting script and updated tests accordingly.
