Drop unused format script

[jhkennedy]

In this PR, I've:

• Removed scripts/format.sh as we currently don't document it and instead use Pre-Commit to run ruff
• Changed "Poetry" to "Pyproject.toml" in scripts/verify_tag.sh as we don't use poetry anymore.

I don't think either of these changes needs a changelog entry.
