This PR removes two CJK punctuation mark from overhang machanism, for following reasons:

1. Punctuation hanging is not usually used in Chinese/Japanese

   In Requirements for Chinese Text Layout, Section 3.1.7 Hanging Punctuation at Line End:

   Most Chinese publications do not use hanging punctuation at line end.

   In Requirements for Japanese Text Layout, Section 3.8.2 Reduction and Addition of Inter-Character Spacing:

   However, line adjustment by hanging punctuation is not an appropriate method for dealing with a mixture of Japanese and Latin script text, since the latter principally does not apply line adjustment by hanging punctuation.

   And the main usecase of LaTeX (and of cause Typst) is mixture of CJK and Latin script text. A search in GitHub shows that only 18 Japanese tex file use the hanging punctuation.

2. Punctuation hanging in Latin languages are fundamentally different from that in Chinese/Japanese.

   Hanging punctuation in Chinese/Japanese is not a visual complement as in Latin languages. In Chinese/Japanese, it is a way of line adjustment to reduce the need to change inter-character spacing.

   See Requirements for Japanese Text Layout, Section 3.8.2 Reduction and Addition of Inter-Character Spacing:
   

   The 1st and 5th line is not hanged, because these lines need not any adjustment.
