This PR adds support for explicitly passing empty string values to PowerShell command arguments when configured to allow them. Previously, empty string arguments were filtered out and not included in generated commands. This enhancement provides more flexibility for PowerShell cmdlets that distinguish between omitted parameters and explicitly empty parameters.

The need has originated from the ability to remove the value set for certain properties this is the way to do it via Powershell.

Test coverage has been added to cover the addition.

Change is a nonbreaking change ensuring existing implementation will not break upon upgrade.

Example:

psCommandService.execute("setContent", {
        Path: "./test.txt",
        Value: "",
        Filter: "*.txt"
})

Currently generating:
Set-Content -Path './test.txt' -Filter '*.txt'

Desired output:
Set-Content -Path './test.txt' -Value '' -Filter '*.txt'

This is archived by marking argument Filter as empty in the commend definition.

  getContent: {
    command: "Get-Content {{{arguments}}}",
    arguments: {
      'Path': {},
      'Filter': {
        empty: true,
      },
    },
    return: {
      type: "text",
    },
  },
