Subject: [PATCH] feat: export private collection config types as public
 aliases

Users annotating parameters like `generative_config`, `reranker_config`,
`vector_index_config`, etc. had to import private `_`-prefixed types,
which pyright strict mode (`reportPrivateUsage: error`) flags as an error.

Adds public TypeAlias entries for the 8 affected types, following the
same pattern as `FilterReturn` introduced in #1993:

- GenerativeConfigCreate   (_GenerativeProvider)
- InvertedIndexConfigCreate (_InvertedIndexConfigCreate)
- MultiTenancyConfigCreate  (_MultiTenancyConfigCreate)
- ObjectTTLConfigCreate     (_ObjectTTLConfigCreate)
- ReplicationConfigCreate   (_ReplicationConfigCreate)
- RerankerConfigCreate      (_RerankerProvider)
- ShardingConfigCreate      (_ShardingConfigCreate)
- VectorIndexConfigCreate   (_VectorIndexConfigCreate)

All 8 aliases are exported from `weaviate.classes.config`.

Closes #1994
