bug#58098: Improve composition rules for Gumrukhi

[समीर सिंह Sameer Singh]

I don't understand this part: why should we require #x1FA67?  Did you
perhaps mean this:

      (chess-symbol . [#x1FA00 #x1FA67])

Isn't the script-representative-chars used to improve font selection by requesting more characters?

So does the specific character requested have any effect? because I chose it randomly.

We already have the setup for chess-symbol, below this line where you
are making changes.  Is it not enough for some reason?

Prior to this patch the chess symbol block was not rendered on my machine despite having its font (Noto Sans Symbols2)
