Argument parser truncates closing parenthesis from string when running on windows in Powershell

### Describe the bug

String parser deletes a closing parenthesis from the string.

I've seen this elsewhere, so I know this is not isolated only to variable creation, but I can repeatedly reproduce it while creating or updating a variable in a variable group.

To reproduce:

0. using windows powershell 7.x
1. create a variable group. get its id
2. run `az pipelines variable-group variable create --group-id --name "myvar" --org --project --value 'thisVarEndsInaParenthesis)'`
4. observe output
```
{
"myvar": {
"isSecret": null,
"value": "thisVarEndsInaParenthsis"
}
}
````
Notice the missing parenthesis at the end of the var value.
5. Navigate to var group in the browser and observe the same missing parenthesis there as well.

### Issue script & Debug output

az pipelines variable-group variable create --group-id --name "myvar" --org --project --secret false --value 'thisVarEndsInaParenthsis)' --debug
--debug was unexpected at this time.

### Expected behavior

Variable is created with its value having a parenthesis at the end.
