manual: replace an obsolete collation example with a valid one
Commit Message
In the Spanish language, the digraph "ll" has not been considered a
separate letter since 1994:
https://www.rae.es/consultas/exclusion-de-ch-y-ll-del-abecedario
Since January 1998 (commit 49891c106244888123557fca7fddda4fa1f96b1d),
glibc's locale data no longer specifies "ch" and "ll" as separate
collation elements. So, it's better to not use "ll" in an example.
Also, the Czech "ch" is a better example as it collates in a more
surprising place.

Thanks, applied.

In some locales, the conventions for lexicographic ordering differ from
