[Bug Report]: Not compatible with latest `pydantic`

### cli command

na

### Extension version

0.2.4

### Describe the bug

It's not compatible with latest `pydantic`. If other dependency installs it, partnercenter fails to load.
See https://github.com/Azure/azure-cli/pull/31967

### To reproduce

Install aks-preview and partnercenter, then run partnercenter command

### Code snippet

```Bicep

```

### Relevant log output

```Shell

```

Start by installing the aks-preview and partnercenter extensions together, then run a partnercenter command to reproduce the load failure. Read the linked Azure CLI pull request for compatibility context and identify the dependency conflict; done means partnercenter loads successfully when another extension installs the latest pydantic.
