[Bug]: Pymilvus requires orjson as a dependency, but it's not declared in pyproject.toml

[zhuwenxing]

Is there an existing issue for this?

• I have searched the existing issues

Describe the bug

 uv pip install -i https://test.pypi.org/simple/ pymilvus==2.7.0rc34
  × No solution found when resolving dependencies:
  ╰─▶ Because orjson was not found in the package registry and pymilvus==2.7.0rc34 depends on orjson>=3.10.15, we can conclude that pymilvus==2.7.0rc34 cannot be used.
      And because you require pymilvus==2.7.0rc34, we can conclude that your requirements are unsatisfiable.

@zhuwenxing
Please use --extra-index-url instead of -i to pip instsall.

-i will download packages in test.pypi only, cannot pull any packages from the default pypi.
