[BUG]: DotNetCoreCLI@2 - Environment Variables

### New issue checklist

- [x] I searched for [existing GitHub issues](https://github.com/microsoft/azure-pipelines-tasks/issues)
- [x] I read [pipeline troubleshooting guide](https://docs.microsoft.com/vsts/build-release/actions/troubleshooting)
- [x] I checked [how to collect logs](https://learn.microsoft.com/azure/devops/pipelines/troubleshooting/review-logs?view=azure-devops)

### Task name

DotNetCoreCLI@2

### Task version

2.X.X

### Issue Description

Inside a job, I have the following steps:

```yaml
  - bash: "echo $(DevExpress_License)"
    env:
      DevExpress_License: "${{ variables.DevExpress_License }}"
  - task: "DotNetCoreCLI@2"
    displayName: "dotnet build"
    env:
      DevExpress_License: "${{ variables.DevExpress_License }}"
    inputs:
      arguments: "--configuration Debug"
      command: "build"
```

And I have a csproj with the following:
```xml
	<Target Name="PrintDevExpressLicence" BeforeTargets="Build">
		<Error Text="DevExpress_Licence - $(DevExpress_License)" />
	</Target>
```


The result is that, the `bash` is able to print the Environment variable.
And the MSBuild not, it fails showing "DevExpress_Licence - ".


The strange part is that sometimes this works.

##[error]Error: The process '/home/voltec/agent/_work/_tool/dotnet/dotnet' failed with exit code 1
##[warning].NET 5 has some compatibility issues with older Nuget versions(<=5.7), so if you are using an older Nuget version(and not dotnet cli) to restore, then the dotnet cli commands (e.g. dotnet build) which rely on such restored packages might fail. To mitigate such error, you can either: (1) - Use dotnet cli to restore, (2) - Use Nuget version 5.8 to restore, (3) - Use global.json using an older sdk version(<=3) to build
Info: Azure Pipelines hosted agents have been updated and now contain .Net 5.x SDK/Runtime along with the older .Net Core version which are currently lts. Unless you have locked down a SDK version for your project(s), 5.x SDK might be picked up which might have breaking behavior as compared to previous versions. You can learn more about the breaking changes here: https://docs.microsoft.com/en-us/dotnet/core/tools/ and https://docs.microsoft.com/en-us/dotnet/core/compatibility/ . To learn about more such changes and troubleshoot, refer here: https://docs.microsoft.com/en-us/azure/devops/pipelines/tasks/build/dotnet-core-cli?view=azure-devops#troubleshooting
