TCH001 false positive in Ruff 0.0.281

[flying-sheep]

When updating to Ruff 0.0.281, the following started falsely throwing TCH001:

playground 1 | playground 2

"""test."""

from __future__ import annotations

from typing import TYPE_CHECKING

from ._support import supported_r_matrix_classes

if TYPE_CHECKING:
    from scipy import sparse


__all__ = [
    "tocsr",
    "supported_r_matrix_classes",
]


def tocsr(obj: sparse.spmatrix) -> sparse.csr_matrix:
    """test."""
    return obj.to_csr()

    from ._support import supported_r_matrix_classes
                          ^^^^^^^^^^^^^^^^^^^^^^^^^^
TCH001: Move application import `._support.supported_r_matrix_classes` into a type-checking block

Probably the same underlying issue as #6207, which should be fixed by #6208.

[flying-sheep]

indeed, duplicate of #6207

This should be fixed in v0.0.282, which is out now.

I'm also going to add Poetry to our ecosystem CI checks, to prevent future regressions.
