 Refactor the NotEmoji rule 
Since we have the ability to use `not` as a prefix, having rules that
validate negative behaviour makes them a bit inflexible, verbose, and
harder to understand.

This commit will refactor the `NotEmoji` and rename it to `Emoji`. It
will no longer check if the string contains emojis, but rather if the
string is an emoji or not. I’m also adding support to more emojis, since
the rule was a bit outdated.

This change will make the validator more strict, but will make it useful
in other scenarios. However, later on, I would like to create a rule
called `has` which, could use a validator like `Emoji` to check if the
input _has_ emojis.
