Fix Broken Specification Links

[gwillcox-r7]

https://github.com/rapid7/ruby_smb/blob/master/lib/ruby_smb/fscc/file_information/file_id_both_directory_information.rb#L5 link is broken, and now redirects to https://docs.microsoft.com/en-us/openspecs/windows_protocols/ms-fscc/1e144bff-c056-45aa-bd29-c13d214ee2ba. This should be updated to the new link if possible.

Update: This seems to be affecting quite a few bits of the code so it might be better to do a search for msdn.microsoft.com across all files and update the links accordingly in one PR.
