Remove spinner from learning uploader (Qiskit#1415)

Small refactor before Qiskit#1390.

The spinner was fun when the tool was primarily used locally, but now
it's annoying in CI and is an extra dependency. See an example of the
new behaviour in the
[test](https://github.com/Qiskit/documentation/actions/runs/9173882338/job/25223510491#step:5:102).
