Fix black style issues, and pin black version

[robintw]

🧰 Issue

N/A

🚀 Overview:

This PR fixes some black style issues that were causing the CI tests to fail, and pins the black version to the latest stable version (22.1.0) in both the pre-commit config file, and the requirements_dev.txt file.

🤔 Reason:

Get the same black version everywhere we use it (locally and CI)

🔨Work carried out:

• [x] Update requirements.txt
• [x] Update pre-commit config
• [x] Run black
• [x] Tests pass

Confirmations

• [x] I have chosen reviewers for my PR.
• [x] I have chosen an appropriate label for the PR, adding interactive_review if reviewers will need to see UI
• [x] I have extended/updated the documentation in \docs folder
• [x] Any database content changes (Create, Edit, Delete) are recorded in the Log/Changes tables
• [x] Any database schema changes are implemented via alembic revision transitions
• [x] I have completed the mandatory sections of this document.

📝 Developer Notes:

If you're going to be contributing code that you've edited on your local machine @IanMayo, it's probably worth doing a pip install -U black to upgrade. pre-commit should upgrade its version automatically next time it's used.
