Add non existing dict_values into the Dictionary table

Due to :hankey: formatting in RackTable's dictionary.php (see e.g. https://github.com/RackTables/racktables/blob/maintenance-0.20.x/wwwroot/inc/dictionary.php#L512) it's impossible to make automatic REST API calls.

By adding the not (yet) known dict_value to the database this issue can be fixed
