fix: update actions/setup-python to v6.0.0 (#69)

Update actions/setup-python action to use the correct commit hash
for v6.0.0 release (e797f83bcb11b83ae66e0230d6156d7c80228e7c).

The previous hash (0b93645e9fea7318ecaed2b359559ac225c90a20) does
not exist in the public repository and prevented workflows from running.
