Azure CLI [az sentinel alert-rule create] COMMAND error (issue with entity mappings)

### **This is autogenerated. Please review and update as needed.**

## Describe the bug
The 'entity-mappings' parameter of the 'az sentinel alert-rule create' command doesn't seem to be functioning as expected.
I am able to create an analytic rule without passing this parameter. However, I get an error when passing the entity-mappings parameter.

**Command Name**
`az sentinel alert-rule create -g -w -n 0080 --scheduled... `

**Errors:**

See screenshot:

## To Reproduce:
Steps to reproduce the behavior.

- Run the following azure CLI command:
- `az sentinel alert-rule create -g -w -n 100 --scheduled "{alert-rule-template-name:18e6a87e-9d06-4a4e-8b59-3469cd49552e,description:test,display-name:test,enabled:true,query:Heartbeat,query-frequency:P1D,query-period:P1D,severity:High,suppression-duration:P1D,suppression-enabled:false,tactics:[Collection],techniques:[T1005],template-version:1.1.2,trigger-operator:GreaterThan,trigger-threshold:0,entity-mappings:[{entity-type:Host,field-mappings:[{column-name:Computer,identifier:FullName}]}]}"`
- The result of this command is unsuccessful- when passing the entity mappings parameter

## Expected Behavior
The following command (identical to the above cmd- minus the passing of the entity-mapping parameter) works fine:
`az sentinel alert-rule create -g -w -n 001 --scheduled "{alert-rule-template-name:18e6a87e-9d06-4a4e-8b59-3469cd49552d,description:test,display-name:test-rule,enabled:true,query:Heartbeat,query-frequency:P1D,query-period:P1D,severity:High,suppression-duration:P1D,suppression-enabled:false,tactics:[Collection],techniques:[T1005],template-version:1.1.2,trigger-operator:GreaterThan,trigger-threshold:0}"`
