feat: export private collection config types as public aliases

[LijuanTang94]

Summary

Closes #1994

Users who want to type-annotate parameters like generative_config, reranker_config, vector_index_config, etc. in collection.create() currently have to import private _-prefixed types. In pyright strict mode (reportPrivateUsage: error) this is flagged as an error.

This PR follows the exact same pattern as #1993 (FilterReturn) and adds public TypeAlias entries for the 8 affected types from collections/collections/executor.py:

Public alias	Private type
GenerativeConfigCreate	_GenerativeProvider
InvertedIndexConfigCreate	_InvertedIndexConfigCreate
MultiTenancyConfigCreate	_MultiTenancyConfigCreate
ObjectTTLConfigCreate	_ObjectTTLConfigCreate
ReplicationConfigCreate	_ReplicationConfigCreate
RerankerConfigCreate	_RerankerProvider
ShardingConfigCreate	_ShardingConfigCreate
VectorIndexConfigCreate	_VectorIndexConfigCreate

All 8 aliases are re-exported from weaviate.classes.config.

Before

# pyright error: reportPrivateUsage
from weaviate.collections.classes.config import _GenerativeProvider

def my_helper(gen: Optional[_GenerativeProvider]) -> ...:
    ...

After

from weaviate.classes.config import GenerativeConfigCreate

def my_helper(gen: Optional[GenerativeConfigCreate]) -> ...:
    ...

Changes

• weaviate/collections/classes/config.py — 6 new TypeAlias entries
• weaviate/collections/classes/config_object_ttl.py — add TypeAlias import + 1 alias
• weaviate/collections/classes/config_vector_index.py — add TypeAlias import + 1 alias
• weaviate/classes/config.py — import and re-export all 8 aliases in __all__
