Renamed executable file does not detect as executable

[Rocky-Moon]

Describe the bug If I rename a file calc.exe -> calc.png and then upload it, it's not detected as executable.

To Reproduce Rename an exe file to another file extension, eg: calc.exe -> calc.png and then upload and try to detect it as executable:

        if (stream.Is<Executable>() || stream.Is<ExecutableAndLinkableFormat>())
        {
            return new ValidationResult("Invalid file was detected.");
        }

Expected behavior I would expect the file to be still be detected as an executable.
