Subject: [PATCH] Remove RenderEmojiPlain from template helper (#29375)

RenderEmojiPlain(emoji.ReplaceAliases) should be called explicitly for
some contents, but not for everything.

Actually in modern days, in most cases it doesn't need such
"ReplaceAliases". So only keep it for issue/PR titles.

If anyone really needs to do ReplaceAliases for some contents, I will
propose a following fix.
