Generated bicepParams file is not correct for the following cases

[ouldsid]

One additional behavior change this will introduce is that a default of "" will be used for any parameter using a user-defined type if I'm reading this correctly. For example, I believe the following template:

param foo {
  requiredProperty: string
  optionalProperty: string?
}

will generate a .bicepparam file of

param foo = ''
