Description

Good day.
I just created a new tap using the cookiecutter template, and the isort version is not compatible with the python version specified in the pyproject.toml. This was likely introduced here: #1360

Error from poetry install right after creating the project:

The current project's Python requirement (>=3.7.1,<3.12) is not compatible with some of the required packages Python requirement:
  - isort requires Python >=3.8.0, so it will not be satisfied for Python >=3.7.1,<3.8.0

@longtomjr A temporary workaround is to change the isort requirement in pyproject.toml in the generated project to a compatible version:

- isort = "^5.12.0"
+ isort = "^5.11.5"

then run poetry lock
