Subject: [PATCH] feat(search): add missing RediSearch stemmer languages

Add Armenian, Hindi, Malay, Serbian, Tagalog and Yiddish to
REDISEARCH_LANGUAGE. These are supported by the RediSearch Snowball
stemmer but were missing from the client enum, so they could not be
passed to the LANGUAGE / LANGUAGE_FIELD options of FT.CREATE and
FT.SEARCH in a type-safe way.

Malay and Tagalog ship with the 8.10 query engine; Armenian, Hindi,
Serbian and Yiddish were already listed as supported languages in the
RediSearch documentation.
