Description of changes:
Removed unnecessary reference to global variable $Name in _packageProject private PowerShell function.
Command dotnet lambda package doesn't have argument --name. Refer below output of dotnet lambda package --help:

Amazon Lambda Tools for .NET Core applications (5.11.0)
Project Home: https://github.com/aws/aws-extensions-for-dotnet-cli, https://github.com/aws/aws-lambda-dotnet

package:
   Command to package a Lambda project either into a zip file or docker image if --package-type is set to "image". The output can later be deployed to Lambda with either deploy-function command or with another tool.

   dotnet lambda package [arguments] [options]
   Arguments:
      <ZIP-FILE> The name of the zip file to package the project into
   Options:
      --disable-interactive                   When set to true missing required parameters will not be prompted for.
      --region                                The region to connect to AWS services, if not set region will be detected from the environment.

      -f     | --framework                    Target framework to compile, for example netcoreapp3.1.
      -farch | --function-architecture        The architecture of the Lambda function. Valid values: x86_64 or arm64. Default is x86_64
      --msbuild-parameters                    Additional msbuild parameters passed to the 'dotnet publish' command. Add quotes around the value if the value contains spaces.
      -fl    | --function-layers              Comma delimited list of Lambda layer version arns
      -o     | --output-package               The zip file that will be created with compiled and packaged Lambda function.
      -dvc   | --disable-version-check        Disable the .NET Core version check. Only for advanced usage.
      -pt    | --package-type                 The deployment package type for Lambda function. Valid values: image, zip

      -ucfb  | --use-container-for-build      Use a local container to build the Lambda binary. A default image will be provided if none is supplied.
      -cifb  | --container-image-for-build    The container image tag (with version) to be used for building the Lambda binary.
      -cmd   | --code-mount-directory         Path to the directory to mount to the build container. Otherwise, look upward for a solution folder.

_packageProject PS function is perhaps mapping $Name global value to dotnet lambda package <ZIP-FILE> argument. However, this value is not necessary, since:

• In PackageCommand,
  • <ZIP-FILE> argument value is used for OutputPackageFileName.
  • OutputPackageFileName is set to different value here if LambdaDefinedCommandOptions.ARGUMENT_OUTPUT_PACKAGE (--output-package) is set.
• $OutputPackage parameter is mandatory
  • In _packageProject function here
  • In New-AWSPowerShellLambdaPackage function here.

Agree the $Name has no meaning. Even if it was set it would be overridden by the $OutputPackage switch below.
