Convert UseSingularNouns to configurable rule and add Windows to allowlist by MJVL · Pull Request #1858 · PowerShell/PSScriptAnalyzer

I'd be happy to accept it as-is but I am thinking it might be better to expose this allowList as a configurable setting so it can be overridden similar to how we decided to do for this rule when allow-listing az: https://github.com/PowerShell/PSScriptAnalyzer/pull/1846/files#diff-0c1b69454498d51fc5f5ba732f2589578f37357dd80b111e8330fff529036908

I agree, as this could cut down on any future issues asking for additional allowList nouns. I can look into refactoring this as a configurable rule.

For the default value, do you think it would still be proper to include {"Data", "Windows"}, or would it be better practice to leave this blank entirely?
