DetectIdentifiers parsing decimals with suffix are considered as Identifier

[tyl24]

Hello, In the DetectIdentifiers method an expression like this one : "amount=Math.Round(455.7 * (0.2m/1000))" considere that the decimal suffix m is an unknownIdentifier, which is wrong ! This behaviours was not the case in previous version 2.13.

In file Detector.cs, I propose to change the RegEx :IdentifiersDetectionRegex like this : (?<id>@?(?<!\d)(?<!\dm)(?<!\df)(?<!\dd)[\p{L}\p{Nl}_][\p{L}\p{Nl}\p{Nd}\p{Mn}\p{Mc}\p{Pc}\p{Cf}_]*)
