Fixes pygraphviz failure when building wheels

One needs to install graphviz over the system package manager before
installing pygraphviz to prevent an automatic build that fails. This can
is achieved widh `sudo apt-get install graphviz graphviz-dev`.

We also add the `workflow_dispatch` event so we can run the workflow
manually.
