\greeknumeral{6} use uppercase glyph instead of lowecase

[Doc73]

Dear devs,
I noticed, actually a long time ago, that the command in question \greeknumeral{6} (with its uppercase counterpart \Greeknumeral{6}) does not distinguish between uppercase (03DA) and lowercase (03DB) glyphs.

This happens with all fonts I tested.

Here is a sample with Libertinus:

% !TeX TS-program = xelatex
% !TeX encoding = UTF-8
% !TeX spellcheck = it_IT

\documentclass[11pt,b5paper,article]{memoir}
\usepackage[]{libertinus-otf}
\usepackage[babelshorthands=true]{polyglossia}
	\setdefaultlanguage[variant=ancient]{greek}

\begin{document}
	\greeknumeral{1}
	\Greeknumeral{1}
	
	\greeknumeral{6}
	\Greeknumeral{6}
	
	\greeknumeral{16}
	\Greeknumeral{16}
\end{document}

Many thanks in advance!

Can you check if the commit I just pushed to master is correct?

Perfect! Thanks!
Too bad I didn't think about reporting this bug years ago! 😄
