Removed erroneous parameter resulting in PlantUML server URL not being used

[docbobo]

Description

When calling into markdown-it-plantuml an additional parameter was being passed that results in custom PlantUML server configs not being picked up. A few lines lower is similar code for dittaa (via PlantUML server) that is missing this parameter and that works correctly

@Rokt33r: this seems to be a trivial change, especially if you realize that code similar to this on line 197 is already working.
