DEV - Miscellaneous enhancements to CI (#1928)

This PR includes a couple of fixes to the CI workflows:

- Moves the installation of Graphviz to our reusable setup action and
uses third-party action
- Ensures Graphviz is installed in the a11y tests
- Adds a note about needing to install Graphviz to build our
documentation
- Re-adds CI permissions for the coverage action (that has led to fails
in our scheduled CI
https://github.com/pydata/pydata-sphinx-theme/actions/workflows/publish.yml)
