[sphinx-build is mia](https://github.com/pysal/pysal/actions/runs/13077718562/job/36493853514#step:5:9) I think it was [removed](https://github.com/pysal/pysal/commit/f7aecbf7e64090e3f00cac256f3235e8235ae399#diff-1d50b0d38cd6e9ca15223971cdabfb4550106487877aaec1386ad1e307da4e13L62) but not replaced elsewhere in the build workflow?
