vectorcode.chromadb: enable check phase

Using a subset of disabled tests from the base package, as others only
apply to >1.0

---

Additionally, disable test_chroma.py and test_client.py:

These tests have issues running in parallel, such as when building the
python 3.12 and 3.13 versions simultaneously.

E.g. when running nixpkgs-review or unlucky timing in hydra.

Usually issues show up as:
    ValueError: An instance of Chroma already exists for ephemeral with different settings
