pythonPackages.tables: 3.6.0 -> 3.6.1 (#72930)

The package has vanished from pypi, and only this new version is now
available. The release notes for the new version state:

```
Release 3.6.1
Maintenance release to fix packaging issues.
No new features or bug fixes.
```

so I can only assume that the 3.6.0 release was not working correctly.
