[extension] blueprint version 0.3.2 - Expect <class 'str'>, got ['Owner', 'Contributor', 'Reader'] (<class 'list'>)

### Describe the bug

the problem is only in the latest extention version of blueprint v0.3.2

no issue in v0.3.1

### Related command

```
az blueprint version list -m --blueprint-name
```

### Errors

When the blueprint version stays as old version, such as `0.3.1`, the command is fine

```
$ az version
{
"azure-cli": "2.51.0",
"azure-cli-core": "2.51.0",
"azure-cli-telemetry": "1.1.0",
"extensions": {
"aks-preview": "0.5.149",
"automation": "0.2.1",
"azure-devops": "0.26.0",
"bastion": "0.2.5",
"blueprint": "0.3.1",
"communication": "1.7.2b1",
"express-route-cross-connection": "0.1.1",
"interactive": "0.5.1",
"logic": "0.1.7",
"ssh": "2.0.0",
"virtual-wan": "0.2.17"
}
}
```

But after I upgrade to latest,
```
az extension add -y --upgrade --name blueprint
Extension 'blueprint' 0.3.1 is already installed.
It will be overridden with version 0.3.2.
```
The command `az blueprint version list xxx` failed with an unexpected error. Here is the traceback:

```
