ci: Install pytz for Pandas nightly wheel

QuLogic · QuLogic · commit 12f8626b58a5 · 2023-03-11T04:53:19.000-05:00
At some point, one of our dependencies must have required `pytz`, but then recently dropped it. Pandas also requires it, but because we install the nightly wheels using `--index-url`, `pip` can only install files from that index, which does not contain `pytz`. And we want to use that index exclusively because we only want the nightly wheels, and nothing else. Also, make `-i` into the more explicit `--index-url`, and word-wrap that step. Fixes #25431
