az policy definition create with parameter in rules

**Describe the bug**
The error occurs when a policy is created that includes a parameter in the rules. If there is no policy, then the command works as expected. It looks like there is a quoting issue.
`
C:\Users\****>az policy definition create --name test --description "A test policy" --mode Indexed --rules "\"if\": { \"not\": { \"field\": \"type\", \"in\": \"[parameters('allowedTypes')]\" } }, \"then\": { \"effect\": \"deny\"}" --parameters "\"allowedTypes\": { \"type\": \"array\", \"metadata\": { \"description\": \"The list of resource types that can be deployed\", \"strongType\": \"resourceTypes\", \"displayName\": \"Allowed types\" }, \"defaultValue\": [ \"Microsoft.Web/sites\"] }"
]\" } }, \"then\": { \"effect\": \"deny\"}" was unexpected at this time.
C:\Users\****> "C:\Program Files (x86)\Microsoft SDKs\Azure\CLI2\wbin\\..\python.exe" -IBm azure.cli policy definition create --name test --description "A test policy" --mode Indexed --rules "\"if\": { \"not\": { \"field\": \"type\", \"in\": \"[parameters('allowedTypes')]\" } }, \"then\": { \"effect\": \"deny\"}" --parameters "\"allowedTypes\": { \"type\": \"array\", \"metadata\": { \"description\": \"The list of resource types that can be deployed\", \"strongType\": \"resourceTypes\", \"displayName\": \"Allowed types\" }, \"defaultValue\": [ \"Microsoft.Web/sites\"] }"
`
The policy can be defined if JSON files are used instead.

**To Reproduce**
Run:
`az policy definition create --name test --description "A test policy" --mode Indexed --rules "\"if\": { \"not\": { \"field\": \"type\", \"in\": \"[parameters('allowedTypes')]\" } }, \"then\": { \"effect\": \"deny\"}" --parameters "\"allowedTypes\": { \"type\": \"array\", \"metadata\": { \"description\": \"The list of resource types that can be deployed\", \"strongType\": \"resourceTypes\", \"displayName\": \"Allowed types\" }, \"defaultValue\": [ \"Microsoft.Web/sites\"] }"`

**Expected behavior**
If the policy rules are implemented correctly, then the policy definition should work as expected.

**Environment summary**
Installed using the Windows MSI installer and then upgraded using the CLI upgrade option.
