Static code validation for python projects failing

[pravindahal]

Eg: https://github.com/coopnorge/python-bigquery-extras/actions/runs/6920199806/job/18824420755

poetry run mypy --show-error-codes --show-error-context --pretty ./src ./tests ./docs
Warning: Found deprecated key 'default' or 'secondary' in pyproject.toml configuration for source engineering-pypi. Please provide the key 'priority' instead. Accepted values are: 'default', 'primary', 'secondary', 'supplemental', 'explicit'.
Warning: Found deprecated priority 'secondary' for source 'engineering-pypi' in pyproject.toml. Consider changing the priority to one of the non-deprecated values: 'default', 'primary', 'supplemental', 'explicit'.
Warning: In a future version of Poetry, PyPI will be disabled automatically if at least one custom source is configured with another priority than 'explicit'. In order to avoid a breaking change and make your pyproject.toml forward compatible, add PyPI explicitly via 'poetry source add pypi'. By the way, this has the advantage that you can set the priority of PyPI as with any other source.

The culprit was status check wrongly reported as successful even though the build skipped for this dependabot update: https://github.com/coopnorge/python-bigquery-extras/pull/282.

https://github.com/coopnorge/python-bigquery-extras/pull/295 reverts the library back to when it was succeeding. While the builds will succeed for now, we need to make sure that the mypy checks are updated to fix this permanently.

Updating to latest mypy causes this issue: https://github.com/coopnorge/python-bigquery-extras/pull/292
