test(python): regenerate lindera ipadic fixtures for lindera 3.x

lance v7.0.0-beta.9 bumps lindera 0.44 -> 3.0.7, which changed the
tokenizer config schema (dictionary is now a string path, not a
{ path: ... } map) and the dictionary binary format (now requires
metadata.json). The old fixtures broke test_fts_lindera_tokenizer on
all platforms.

Lift the regenerated config.yml and main.zip from the lance
v7.0.0-beta.9 tag (lance-format/lance#6719) and update the
lindera_ipadic fixture's config writer to the 3.x schema.
