Clearly point to the documentation

[Beep6581]

Search the internet for "orca slicer wiki" or "orca slicer documentation".

You land in this wiki, which looks dead and would drive me away as a new user: https://wiki.orcaslicer.com/wiki/Home

In reality, this seems the official documentation: https://github.com/SoftFever/OrcaSlicer/wiki

To close this issue, have wiki.orcaslicer.com redirect to https://github.com/SoftFever/OrcaSlicer/wiki
