Support C4PlantUML borderStyle and borderThickness

[qtzar]

Description

C4 PlantUML V2.8.0 has added the capability to set the border style and border thickness on elements and boundaries.

I would like to be able to utilize these new values so that I can create new styles for tags like 'new' and 'depricated' so that I can produce future state diagrams that stand out from current state.

Priority

Medium

Resolution

I'm willing to add this feature myself and raise a PR

More information

This looks like a simple enough change to add the two new properties to the export based on the current style ( similar to how borderColor is currently done ).

I will attempt a PR for the changes.

May not be able to do this till the PlantUML library is updated to include the new C4 StdLib files.

edit : I have the code ready for this but won't do a PR till I see PlantUML library is updated.
