Build from source (e.g. via pre-commit) is broken by new poetry version

[mhsmith]

Poetry-core 1.5.0, which was released 30 minutes ago, adds additional validation for the extras section, which causes this error when installing from source:

% pip install --no-binary :all: -U isort
DEPRECATION: --no-binary currently disables reading from the cache of locally built wheels. In the future --no-binary will not influence the wheel cache. pip 23.1 will enforce this behaviour change. A possible replacement is to use the --no-cache-dir option. You can use the flag --use-feature=no-binary-enable-wheel-cache to test the upcoming behaviour.

Unfortunately I think this affects everyone who uses isort via pre-commit.

To prevent something like this from happening again, maybe isort's pyproject.toml should pin a specific version of poetry-core.
