VSCode - Enhance "required properties" to generate code with param order

I think it could be useful to have the parameters of a bicep file remember the order they are declared. This way when generating code with a feature like `required properties` it would preserve that order. I find myself constantly reorganizing.

In the example I would expect the module params to be in this order:

1. name
2. location
3. third
4. fourth

but instead results in:

1. fourth
2. location
3. name
4. third

Reproduce the VSCode "required properties" generation behavior with the example parameter declarations, then trace the required properties feature and how it orders module parameters. Done means generated parameters follow their declaration order: name, location, third, fourth, rather than the current order.
