Drop `emojis-title` feature #2035

[emojis-title] takes the alias attribute (provided by GH) of the emoji, and adds it as a title (if any of its closest parent doesn't provide one).

Presumably so that anyone without access to an emoji keyboard (picket) can use this info to insert emojis in comments.

Considering that GitHub already provides autocomplete for emojis in desktop view and that the title attribute is useless on mobile devices, I think this feature can be dropped. 🤷‍♂️
