Avoid using emoji as a collation example

[hsivonen]

Summary

Instead of using emoji as an example of an explicitly-requested collation type, use zhuyin instead.

Motivation

The emoji collation type is intended for charts and emoji pickers and that it combines with a language like English is incidental and works only because English is an alias for the root collation. Notably, it doesn't combine with languages that aren't aliases for the root.

The non-default collation types that have the most present-day use case relevance are probably zhuyin for Traditional Chinese and phonebk for German and of these, phonebooks are arguably more special-casey. Therefore, using zhuyin as the example.
