Added a guide on overriding React component props to trans-component.md

[nico-i]

Motivation / Reason

I spent a large chunk of time stumbling through issues, pull requests and source code in my search for the possibility of passing component props via translation messages.

After finally finishing my research, implementing the discovered functionality was also not 100% straightforward. This in mind, I thought it might aid the next person if a guide for this sort of thing were to exist in the docs.
