Check if toolkit version changed before attempting publish (#198)

# PR Description
Changes to a toolkit without changes to the toolkit's version fail the
'Publish Toolkit' workflow with `HTTP Error 400: File already exists
('arcade_zoom-0.1.7.tar.gz', with blake2_256 hash
'02183cda607f06616e7edb17e3d22bc11d1d83b074b3e44066b78ec72602fb37'). See
https://pypi.org/help/#file-name-reuse for more information.`, for
example.

This PR adds the `--skip-existing` flag to `poetry publish` to avoid
attempting to publish an existing version. Skips slack notification if
publish is skipped.


The `grep`'d string comes from
