Definitions for Information, Warning, and Error Severities

In the code comments for the RuleSeverity enum, a warning does not follow PowerShell's "recommended" guidelines and Errors do not conform to PowerShell's "required" guidelines. Information rules are "recommended by PowerShell best practice".

I just posted #466 and now that I am thinking about it, I am not sure what the specific criteria is that would differentiate Warnings from Errors. For my team, at my company, we cannot have any hard coded passwords in a script, so this would definitely be an Error. However, that might not be the case for everyone everywhere.

The definitions of Warning and Error severity should be clearly defined in the documentation. I have some ideas and opinions here, as I am sure everyone in the PS community does. Would it make sense to use https://github.com/PoshCode/PowerShellPracticeAndStyle as a starting point for best practices and guidelines?

I am also wondering if it would make sense to have the ability to override severity levels for built in rules.

RuleSeverity enum のコメントから始め、issue でリンクされている PowerShellPracticeAndStyle のガイダンスと現在の文言を比較します。Information、Warning、Error の重大度を区別する基準を定義して文書化し、組み込みの重大度オーバーライドを対象に含めるかどうかを明確にします。
