Normalize the lower part to 哥.

About the comment #8629. I assume that the suggestion is to change the 亅 in the top 可 to 丨. That's a reasonable suggestion, but there are at least 6 other V-source characters already encoded (𣘁 U+24819, etc.) that use the current design. Since that's a majority, the lesser impact solution would be to normalize the remaining characters 哥 U+54E5, 歌 U+6B4C, U+2BC04, and VN-F176E (in WS2021) to use 亅.
