Black is not formatting anything

[auscompgeek]

Since #1877, Black is no longer formatting cursorless-talon.

Manually running black on any Python file, or even the entire directory, outputs:

> black cursorless-talon
No Python files are present to be formatted. Nothing to do 😴

Commenting out this line makes Black work as expected again:

cursorless/pyproject.toml

Line 3 in 7369cea

force-exclude = ["vendor", "data/playground"]

> black cursorless-talon
All done! ✨ 🍰 ✨
