Add color support for XCom

[tirkarthi]

Description

When XCcom values are JSON it will be good to have them highlighted and formatted for better readability. Once there is a port of ReactJSON or other approach to copy JSON values the same could be applied here.

Probably should consider this also for Airflow Variables with json?

@tirkarthi Since our UI is relatively stable and ReactJSON has been introduced, I think it's a good time to use the component to support highlighting XComs. Would you mind reviewing my PR for this issue?
