Asyncapi with schema property double throwing in Spectral linting

[tanujazz3]

Hi Team,

I am trying to use spectral linting for my workflow to validate the asyncapi and it's throwing an error for a double type.
Could you please tell me whether double is supported in the data type. Here is the sample snippet with the type highlighted.
