Basic support of "ARMv2" AKA resources as an object

[andyleejordan]

Okay so I tried a bunch of different ways and settled on this being the simplest approach. In short, a custom serde deserializer function let's us take resources as either an array or an object and produce what the existing implementation expects: a Vec<Resource> such that after the initial deserialization, nothing else needs to change. This means that later ordering should work (though when I tested dependsOn in Bicep, I got a different error).

I can at least now pass through this Bicep directly to DSC and it gets to the point that it attempts to execute the resource:

extension dsc
targetScope = 'desiredStateConfiguration'

resource myEcho 'Microsoft.DSC.Debug/[email protected]' = {output: 'Hello world!'}

which produces this ARM/JSON:

{
  "$schema": "https://aka.ms/dsc/schemas/v3/bundled/config/document.json",
  "languageVersion": "2.0",
  "contentVersion": "1.0.0.0",
  "metadata": {
    "_generator": {
      "name": "bicep",
      "version": "0.38.33.27573",
      "templateHash": "9007474339958309780"
    }
  },
  "imports": {
    "dsc": {
      "provider": "DesiredStateConfiguration",
      "version": "0.1.0"
    }
  },
  "resources": {
    "myEcho": {
      "import": "dsc",
      "type": "Microsoft.DSC.Debug/[email protected]",
      "properties": {
        "output": "Hello world!"
      }
    }
  }
}

Perhaps we should gate this behind a feature-flag, but between this and publishing a basic version of the Bicep extension to an MCR, we can resume demos but with fancy IntelliSense and working versions!

For the fields noted as irrelevant, I sure would like to use #[serde(skip)] but it is incompatible with deny_unknown_fields. Perhaps we should revisit that serde flag, possibly using the linked workaround with IgnoredAny and warnings instead of failures.

I have to admit that the additional tests were generated by Claude, though it was pretty good at it!

Shouldn't the schema be: https://aka.ms/dsc/schemas/v3/bundled/config/document.json?

Same here?
