Formatter doesn't indent bracketed multi-line arguments correctly

Bracketed Commandlet arguments spanning multiple lines should increase the indentation level. See Invoke-Bar in the below example.

Expected behavior

Invoke-Foo `
    -Argument (
            Invoke-Bar -Argument
        ) `
    -Argument2

Actual behavior

Invoke-Foo `
    -Argument (
    Invoke-Bar -Argument
) `
    -Argument2

If an unexpected error was thrown then please report the full error details using e.g. $error[0] | Select-Object *

使用 PSScriptAnalyzer，透過 issue 中的 Invoke-Foo 和 Invoke-Bar 範例重現 formatter 輸出。追蹤 formatter 對帶括號的多行命令引數的處理，並檢查現有的 formatter 測試。完成標準是巢狀的 Invoke-Bar 引數按照預期輸出中的顯示進行縮排，且透過測試涵蓋此回歸問題。
