false negatives on Zip file validation

[mrozx]

Describe the bug
Since version 4.2.0 Zip file validation fails (false negative)

To Reproduce
Steps to reproduce the behavior - c# code:
// filebyte bytes array starts with [80,75,3,4...]
bool isValid = FileTypeValidator.Is<FileTypeChecker.Types.ZipFile>(fileBytes);
// isValid is false !!

Expected behavior
isValid should be true

Additional context
Works properly on version 4.1.1. Issue started on version 4.2.0.
Tried to created zip files both with Windows context menu and WinRar Zip Archive. Both ways, the byte array starts the same.

Thanks

I have found the same problem when testing ZIP-ed PDF files, it gets identified as Microsoft Office 365 Document, since it has better score than Zip File.
You can take for example this PDF-file from adobe and simply zip it, and try to run the FileTypeValidator.GetFileType(), and it returns MicrosoftOffice365Document instead of ZipFile.
The problem came from changes in #38 and #41, where were added new magic bytes.
