fix: Use https protocol as unauthenticated git protocol is no longer supported

[matthewfeickert]

Description

Use of the unauthenticated git protocol (git://) is no longer supported on GitHub (c.f. the 2021-09-01 GitHub Security blog Improving Git protocol security on GitHub). As a result, the current HEAD of dependencies workflow fails with the following error.

Collecting git+git://github.com/scikit-hep/uproot4.git

To avoid this, use the https:// for cloning a Git repo.

I'm going to merge this without getting additional sign off as it is a change in Git cloning protocol that we have no choice but to adopt.
