The xlsx2csv@0.8.2 only provides a source distribution which fails to install on Ubuntu 22.04 with the version of pip that comes from python3-pip:

    ubuntu-22.04: ERROR: No matching distribution found for xlsx2csv==0.8.2

xlsx2csv@0.8.2 is the first version in the last bunch that does not provide a .whl build, and so requires a newer version of pip to be installed for now, though ideally upstream could provide a whl and that'd allow us to upgrade (dilshod/xlsx2csv#276).

What is the new behavior?

Reverted to xlsx2csv@0.8.1. Our usage of this module is pretty basic, and the bugfixes included in the latest version don't really affect us, so there's no need to force our upgrade to 0.8.2 at the moment.

Other information?

Vagrant up should succeed: https://github.com/Submitty/Submitty/actions/runs/7800496541
