Update Documentation to New Standard

[BurksEngineering]

TwinCAT 4026 drops support for reStructuredText in favor of the (paid) TE1030 XML-based documentation. As an open source project, TcMatrix is allowed to use the zeugwerk doc generation for free. Either way, the documentation must be updated.

Thank you! I will try to maneuver this change into a 4026 branch instead of the master because of the ProductVersion attribute change.
