Edit zkn-method.md english version

zkn-method.md now states that the ID can be the file name and if the filename has the format of the ID it will take precendence over any ID in the file contents.

 The default ID is a good call, because it uses the date in the format YYYYMMDDHHMMSS, which is unique to the second. Also, our own experiences show that when one doesn't use easy-to-recognise IDs, one is less prone to assume stuff, making them better suited to cross-link files. Just try it yourself!
 
-Zettlr will automatically try to find an ID for a file by searching through its contents. If it has found an ID that is _not_ encapsulated by a Wiki link (more on that below), it will assume this ID internally to refer to the file. If there is more than one valid ID in the file, **the first ID will take precedence**. This way, even in long files, if you can't find the ID, simply drop a new ID on top of the file to make this assume the role of a general ID for the file.
