NoEngineer example: Meta files are now in a different path

[martinboers]

In the NoEngineer example, more recent versions of the PLCnext CLI put the meta files in a different location to the one assumed by the tutorial. As a result, Step 5 of the procedure, and the pnd.meta.config file, needs to be updated.

In the mean time - it doesn't really matter where any of the files are located on the device, what matters is that all the paths in the .config files point to the place where the file(s) are located. For example, the config folder (in the bin folder) can be copied to the directory /opt/plcnext/projects/Pnd on the PLC, and then the pnd.meta.config file can be updated to include the correct path to the Pnd.libmeta file. After that, everything should work ok.
