BulkReplaceAssemblyInfoVersions: F# + VB are respected too now, Sample code snippet added

I changed the code so that it will now also respect AssemblyInfo.fs and AssemblyInfo.vb files.
In addition to that, the AssemblyInfo files do not have to be stored in a "Properties" folder, as many F# projects seem to not use such a folder.
I added a sample code snippet on how to use it in the XML comment, I hope I understood forki's request correct by adding the sample in this way.
