PSAvoidUsingCmdletAliases triggers on GherkinStep

Gherkin (including in Pester) has a few aliases which you are meant to use when creating steps.

Alias           And -> GherkinStep                                 4.2.0      Pester
Alias           But -> GherkinStep                                 4.2.0      Pester
Alias           Given -> GherkinStep                               4.2.0      Pester
Alias           Then -> GherkinStep                                4.2.0      Pester
Alias           When -> GherkinStep                                4.2.0      Pester

These are valid uses of the alias and shouldn't trigger analyzer warnings.

Steps to reproduce

Create a Gherkin (Pester) step file like Blah.Steps.ps1

Given "something" {
}

Then Invoke-ScriptAnalyzer Blah.Steps.ps1

Expected behavior

No issues.

Invoke-ScriptAnalyzer を実行し、PSAvoidUsingCmdletAliases と GherkinStep エイリアスに焦点を当てて、Blah.Steps.ps1 の例で警告を再現します。完了の定義は、Pester Gherkin ステップとして使用される Given、And、But、When、Then では analyzer の問題が生成されず、通常のエイリアスは引き続きルールの対象となることです。
