Subject: [PATCH] Fix bad tox.ini passenv setting (#825)

Fixes https://github.com/Qiskit/qiskit-ibm-provider/pull/821.

I made a divergence from our testing in qiskit-sphinx-theme to make the INI file more readable, and I didn't properly test it. My bad!

This bug meant that we always used `main` as the branch name. I tested this out locally and it works now:

```
GITHUB_REF_NAME="pull" GITHUB_BASE_REF="upstream" tox -e docs
...
    raise ValueError(GITHUB_BRANCH)
ValueError: upstream
```
