Enable custom JAVA Path and command args for plantUML

[CzechJiri]

this is a new feature request, Is there any way to add custom settings for

• JAVA location
• JAVA command arg. specifying the location of dot fie (if Graphviz is used)

It could be similar to how plantUML vscode plugin does it?

"plantuml.java":"path-to-java",
"plantuml.commandArgs":["-DGRAPHVIZ_DOT=path-to-dot"]

I get the same error and need to overwrite the path of the jave executable.

Figured out a temporary workaround:

1. Start PlantUML: Preview Current Diagram
2. Click into the PlantUML diagram in the md page
3. PlantUML starts to render, but the MD contenct will be not shown
