Rule request: Warn when second dot on numeric literal causes member access expression

[iRon7]

Summary of the new feature

See: #15756 Unquoted numbers with two or more dots should cast to a [version] rather than $Null
When an unquoted number contains two or more dots, the second dot is seen as a member separator (rather than an illegal addition decimal separator) which causes the syntax unexpectedly to return $Null without notice:

$Version = 2.0.9
$Null -eq $Version
True

What is the latest version of PSScriptAnalyzer at the point of writing
1.19.1
