fix pypi publishing (#1312)

### Changelog
None
### Docs

None

### Description

See also foxglove/schemas#158.

> Running a publish to TestPyPI immediately followed by a publish to the
"real" PyPI triggered an error due to a file already existing. The
workaround recommended in
pypa/gh-action-pypi-publish#283 (comment)
is to set `attestations: false` on the TestPyPI publish.
