PSAvoidTrailingWhitespace should ignore empty lines indented to match the current block

Currently, PSAvoidTrailingWhitespace checks all lines for trailing whitespace, even when that line is effectively empty and the "trailing" whitespace is actually leading whitespace for the current indentation level. If the recommended action is taken (remove the whitespace), then adding new code in those spots requires re-indenting that spot to the current code indentation level.

I propose that it should respect the current indentation level for an empty line and not generate a note for those lines, as long as they match the indentation of the current block of code.

What is the latest version of PSScriptAnalyzer at the point of writing
1.17.1, shipping with the vscode-powershell extension version 1.8.1

まず、PSAvoidTrailingWhitespace ルールの実装と既存のテストを見つけます。現在のブロックレベルまでインデントされた空行のケースを再現し、一致するインデントは無視される一方で、実際の行末の空白は引き続き報告されることを確認します。テストでこの動作がカバーされ、ルールがこれらのケースを区別できれば完了です。
