Prevent prop s keys to be transformed in render array keys with # in StoriesSyntaxConverter

Thanks you so much Kensae, your solution is very pragmatic, targeting exactly where the issue here in SDC prop conversion.

However, we are currently facing a similar issue in UI Example module: ✨ Support Single directory components Active and I would address to address both:

• in a more generic way, because the root cause is the wrong sue of render children by SDC
• in a similar way in both module

So, I let this in review state for now.
