Assignment of invalid values to local action preference variables

Not global action preference variables are not strongly typed. As a result,
anything can be assigned to them, not necessarily valid values. For example,
typos will not be reported as errors, unlike with global variables.

In other words, PSSA should report issues like this, mind the typo:

$VerbosePreference = 'Cotninue'

首先跟踪 PSScriptAnalyzer 如何处理对 PowerShell 操作首选项变量的赋值，然后查看 Local-ActionPreference 示例及所引用的行为。完成的标准是：无效的本地值（例如拼写错误的 'Cotninue'）会被报告为分析器问题，而有效值仍会被接受。
