Creates an OpenApiConfig from a Node value.

<p>This method first converts deprecated keys into their new locations and
formats, and then uses the {@link NodeMapper} on the converted input
object. Note that this class can be deserialized using a NodeMapper too
since the NodeMapper will look for a static, public, fromNode method.

<p>This method also serializes unknown properties into the
"extensions" map so that they are accessible to OpenAPI mappers.

@param input Input to deserialize.
@return Returns the deserialized OpenApiConfig.
