test: replacing each DocumentStore specific tests and used the generalised ones from haystack.testing.document_store

• fixes Avoid duplicating test code in DocumentStore integrations #2811

Proposed Changes:

• Use Haystack’s shared document store test mixins (DeleteDocumentsTest, UpdateByFilterTest, etc.) instead of custom duplicated tests across integrations.

Document store	# duplicated tests removed
Astra	3
Azure AI Search	6
Chroma	4
Elasticsearch	3
MongoDB Atlas	4
OpenSearch	3
pgvector	8
Pinecone	7
Qdrant	8
Weaviate	3

Total tests removed: 49. and 7 overrides tests added in Azure AI Search

• Bug fixes
  • Chroma: Guard delete_all_documents() so it doesn’t call delete(ids=[]) on an empty collection (avoids Chroma error when there are no docs).
  • Azure AI Search: Handle booleans in filter helpers _eq / _ne in filters.py (e.g. true/false in OData).
  • Azure AI Search: Conftest update_by_filter_and_wait updated to accept meta (and fields/kwargs) and pass the correct updates into update_by_filter.

How did you test it?

• Run each integration’s document store tests (e.g. pytest integrations/<name>/tests/test_document_store.py).
• Confirm no custom delete/update-by-filter tests remain except where overrides are required (e.g. parametrized metadata or backend-specific options).

Notes for the reviewer

• This PR must be merged only after test: add delete_all_documents, delete_by_filter and update_by_filter generic tests to haystack.testing.document_store haystack#10477 is merged in haystack
• Currently every pyproject.toml is using this branch test: add delete_all_documents, delete_by_filter and update_by_filter generic tests to haystack.testing.document_store haystack#10477 - before this PR is approved those need to be updated to point to the latest haystack release
