Not all functions with a Path parameter have a LiteralPath parameter

[ThomasNieto]

Not all the functions that have a Path parameter have a corresponding LiteralPath parameter. Found this while implementing #53.

Steps to reproduce

$functions = Get-Command -Module PowerShellGet -ParameterName Path

foreach ($fun in $functions) {
    It "$fun should have a LiteralPath parameter" {
        Get-Command -Name $fun.Name -ParameterName LiteralPath -ErrorAction SilentlyContinue | Should -Not -BeNullOrEmpty
    }
}

Expected behavior

Executing script C:\test\LiteralPath.tests.ps1
  [+] New-ScriptFileInfo should have a LiteralPath parameter 22ms
  [+] Publish-Module should have a LiteralPath parameter 1ms
  [+] Publish-Script should have a LiteralPath parameter 2ms
  [+] Save-Module should have a LiteralPath parameter 2ms
  [+] Save-Script should have a LiteralPath parameter 2ms
  [+] Test-ScriptFileInfo should have a LiteralPath parameter 1ms
  [+] Update-ModuleManifest should have a LiteralPath parameter 1ms
  [+] Update-ScriptFileInfo should have a LiteralPath parameter 1ms
