DdckPlaceHolderValues.json not added to run.config during automated export.

[ahobeost]

As a User, I would like the automated export to include everything I need to run a system out of the box.
Currently, the DdckPlaceHolderValues.json is not linked to during the automated export.

string pathToConnectionInfo ".\DdckPlaceHolderValues.json"

This leads to the following unhelpful message:
No default values were provided for the computed variables at the following locations (line number:column number):

This feedback could also be improved to point to the flag.

Overall, I think that we should now be ready to including this location as the default.

Adding the pathToConnectionInfo flag would then only be needed if it is placed elsewhere.
The latter is highly unlikely imo.
