fix(css_counter_style): correct Hebrew Gimel and Dalet characters.

[YOSEFTT]

Subject: Fix incorrect Hebrew characters for 'Gimel' and 'Dalet' in css_counter_style.dart

Description:
Hi,
I noticed a small bug in the Hebrew numeral system implementation within packages/css_counter_style.dart. It seems that the characters for the numbers 3 (Gimel) and 4 (Dalet) were accidentally represented using characters from other alphabets instead of Hebrew.

Current (Incorrect) code:
(4, 'դ'), // This is an Armenian 'da'
(3, 'გ'), // This is a Georgian 'gan'

Corrected code:

(4, 'ד'), // Hebrew Dalet
(3, 'ג'), // Hebrew Gimel

Changes:

• Replaced the Georgian character გ (U+10D2) with the Hebrew letter ג (U+05D2).
• Replaced the Armenian character դ (U+0564) with the Hebrew letter ד (U+05D4).

This fix ensures that ordered lists using the Hebrew numbering system are displayed correctly.
Best regards,
YOSEFTT
