[BUG] Development pre-commit hooks throwing error

[RayDanks]

Describe the bug
A change in Poetry means that the current version of isort is throwing errors - see below for the traceback:

`[INFO] Stashing unstaged files to /home/user/.cache/pre-commit/patch1676831322-474.

  note: This error originates from a subprocess, and is likely not a problem with pip.

The issue was described in this GitHub comment, as well as the hotfix:
PyCQA/isort#2083 (comment)

To Reproduce

1. Install dev requirements as described in contributing.md
2. Run pre-commit install, which should complete successfully
3. Make a change to the repo, and commit using: git commit -m "any message"

Expected behavior
The pre-commit hooks should check the commit and complete correctly.

System (please complete the following information):

• Python version: 3.10.6
• darts version Current master branch, not installed via manager

Additional context
This issue is because the repo specifies that the isort used is version 5.10.1. The solution to this problem, as described in the attached issue comment, is to upgrade isort to version 5.11.5, to include the hotfix. I have done this in the following PR:
#1578
