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，通过 issue 中的 Invoke-Foo 和 Invoke-Bar 示例重现 formatter 输出。跟踪 formatter 对带括号的多行命令参数的处理，并检查现有的 formatter 测试。完成标准是嵌套的 Invoke-Bar 参数按照预期输出中的显示进行缩进，并且通过测试覆盖该回归问题。
