AvoidAssignmentToAutomaticVariable doesn't distinguish between normal and DSC scripts

The AvoidAssignmentToAutomaticVariable rule doesn't distinguish between a normal script and a DSC script, meaning DSC specific auto-variables like $allNodes will cause complaints when the rule runs. I don't know if this is even something that could have logic applied to it in an effort to suppress, given there isn't necessarily an easy way to discern context of DSC vs Non-DSC scripts

Steps to reproduce

Create a standard powershell script ps1 file and enter the following. If in VS Code PSScriptAnalyzer automatically runs against it.

$allNodes = "Put anything here"

Expected behavior

Rule does not complain about usage of $allNodes as script is not used in DSC.

Actual behavior

The Variable 'allNodes' is an automatic variable that is built into PowerShell, assigning to it might have undesired side effects. If assignment is not by design, please use a different name.

从 AvoidAssignmentToAutomaticVariable 规则开始，使用包含对 $allNodes 赋值的标准 PowerShell .ps1 重现该问题。确定该规则是否能够区分 DSC 脚本和普通脚本，然后验证普通脚本的情况下不再报告此变量，同时不改变预期的 DSC 行为。
