Summary

The document schema requires 1 item in the resources array, but dsc.exe will accept and generate documents with an empty resources array.

https://github.com/PowerShell/DSC/blob/d769405dc3cc70f8c8baaf2b4708b47aacdabe00/schemas/v3.0.0/config/document.json#L42-L46

The minItems should be either removed or set to 0.

Steps to reproduce

1. Have a resource (ResourceWithNoState) that can export with no state configured so that it produces no output (or just create a resource manifest with export and point it at an executable that will produce no output).
2. Run dsc resource export -r ResourceWithNoState

# Output from: dsc resource export -r ResourceWithNoState

$schema: https://aka.ms/dsc/schemas/v3/bundled/config/document.json
contentVersion: 1.0.0
resources: []

Piping that back into dsc like dsc resource export -r ResourceWithNoState | dsc config test -f - also succeeds:

# Output from: dsc resource export -r ResourceWithNoState | dsc config test -f -

PS Another bonus issue: dsc searches all adapters for resources despite not needing to find any, leading to this empty test taking anywhere from 6 to 28 seconds.

Expected behavior

The schema definition for resources matches the observed behavior which has no minimum item requirement.

Actual behavior

An empty resources array is allowed, but the schema requires 1 item.
