[Shell] Azure CLI receives corrupted arguments in PowerShell

## Describe the bug

When invoking `az` in PowerShell, due to the known issue of PowerShell https://github.com/PowerShell/PowerShell/issues/1995, arguments passed to Azure CLI may get corrupted. For example, literal double quotes (`"`) are lost:

```pwsh
# PowerShell
> az '{"signInAudience":"AzureADAndMicrosoftAccounts"}' --debug
Command arguments: ['{signInAudience:AzureADAndMicrosoftAccounts}', '--debug']
```

This contradicts the behavior of Bash:

```sh
# Bash
$ az '{"signInAudience":"AzureADAndMicrosoftAccounts"}' --debug
Command arguments: ['{"signInAudience":"AzureADAndMicrosoftAccounts"}', '--debug']
```

## Impact

This is mainly affecting

- passing JSON as an argument as in `az rest --body {JSON}` (#15512)
```powershell
# not working
az rest ... --body '{"signInAudience":"AzureADandPersonalMicrosoftAccount"}'
# working
az rest ... --body '{\"signInAudience\":\"AzureADandPersonalMicrosoftAccount\"}'
```
- using JMESPATH `--query` (#13152)
```powershell
# not working
az version --query '"azure-cli"'
# working
az version --query '\"azure-cli\"'
```
