[Built-in rule] Add SystemAssigned, UserAssigned as an allowed identity on TA-000007, TA-000013, TA-000019

[richardsondev]

Description

Add SystemAssigned, UserAssigned as an accepted identity on rules TA-000007, TA-000013, TA-000019. This is a valid operation on Azure Functions and currently our bicep templates are being flagged by this so we need to ignore this rule.

Issue #372

Expected behavior

TA-000013 should not detect Azure Functions as missing an identity when both SystemAssigned and UserAssigned are defined:

  identity: {
    type: 'SystemAssigned, UserAssigned'
    userAssignedIdentities: {
      '${managedIdentity.id}': {}
    }
  }
