Description

poetry version 1.5.0 broke installs of isort prior to 5.11.5 (see PyCQA/isort#2077 and PyCQA/isort#2078), so we need to upgrade.

Is this needed across the board in RAPIDS repos? Is it crucial for 23.02?

almost everywhere (some repos don't use isort afaict); CI is broken (no code stops working) without this change since it is not possible to set up the pre-commit environment with older isort versions any more (they may backport a fix, but haven't done so yet)
