Invoke-ScriptAnalyzer required Path parameter

The required -Path parameter is a usability concern. It should default to . removing the need for the required parameter.

Invoke-ScriptAnalyzer

Actual behavior

Invoke-ScriptAnalyzer

cmdlet Invoke-ScriptAnalyzer at command pipeline position 1
Supply values for the following parameters:

首先定位 Invoke-ScriptAnalyzer 命令的实现及其 Path 参数的定义。检查省略 Path 时命令的行为，然后验证不带参数调用 Invoke-ScriptAnalyzer 会针对当前目录运行，且不会提示输入 Path。
