Update essential-syntax.md

[thimanshu1993]

Added an explanation of Left, Top, Right, and Bottom value ordering in XAML syntax.

I'm not sure if this is necessary here. A detailed explanation of this is already available here

@bhavanesh2001 Yeah, I'd recommend just replacing what you added with a link to the relevant section of the doc you identified.

Hi @davidbritch,

Thank you for your valuable feedback! My intention was to provide readers with a bit more clarity upfront. Given that the title is "Essential XAML Syntax," I felt that, from a new user's perspective, this particular point had minimal explanation.

That said, I have incorporated your feedback and added a small note with a reference link. I hope this works well—please let me know if any further refinements are needed.

Thanks again!
