[TST]: speed up test_embeddings.py against cluster

[codetheweb]

Description of changes

Speeds up test_embeddings.py against the cluster: ~25m -> ~16m. The test is now parallelized and checks for new collection versions at a higher frequency (the collection version change has the side effect of also speeding up test_filtering.py).

Test plan

How are these changes tested?

• Tests pass locally with pytest for python, yarn test for js, cargo test for rust

• Can you think of any inputs or external events that could break the code? Is user input validated and safe? Have they been tested?
• If appropriate, are there adequate property based tests?
• If appropriate, are there adequate unit tests?
• Should any logging, debugging, tracing information be added or removed?
• Are error messages user-friendly?
• Have all documentation changes needed been made?
• Have all non-obvious changes been commented?

System Compatibility

• Are there any potential impacts on other parts of the system or backward compatibility?
• Does this change intersect with any items on our roadmap, and if so, is there a plan for fitting them together?

Parallelize and Accelerate test_embeddings.py for Cluster Execution

This PR optimizes and parallelizes the property-based test suite test_embeddings.py when run against a cluster, reducing runtime significantly (~25m to ~16m). Key improvements include more frequent polling for collection version changes, centralization of isolated database creation, and updates to related utils and workflow configuration to further accelerate other tests (e.g., test_filtering.py). The isolated database setup logic is now shared and reused across test modules, reducing overhead and inter-test dependencies.

Key Changes:
• Moved create_isolated_database utility from test_add.py to conftest.py for central test use.
• Updated test_embeddings.py and test_add.py to use create_isolated_database, improving test isolation.
• Modified wait_for_version_increase.py to decrease TIMEOUT_INTERVAL from 5 to 1 second for faster polling.
• Refactored workflow YAML to parallelize test_embeddings.py (in addition to test_add.py) in cluster jobs.
• Removed redundant/duplicated isolated database code and updated imports accordingly.

Affected Areas:
• chromadb/test/property/test_embeddings.py
• chromadb/test/property/test_add.py
• chromadb/test/conftest.py
• chromadb/test/utils/wait_for_version_increase.py
• .github/workflows/_python-tests.yml
