VersionExtensions Regex does not support package ID ending with numbers

Hi,

if you use NuGet Package Explorer and your nuget package id ends with a number updates won't work anymore (caused by changes in VersionExtensions.cs for prerelease support).

The NuGet Package Explorer uses a point to seperate the package id from the version number (at least if you don't change the filename).

ID: MyId123 Version: 1.1.0

The result would be "MyId123.1.1.0.nupkg"

The suffix regex will remove ".nupkg" and the version regex will match "123.1.1.0" instead of "1.1.0".

A workaround would be renaming your NuGet Package to "MyId123-1.1.0.nupkg". The code should be changed or this naming issue should be noted somewhere.
