Temporary fix for failing checks on github

[imagoulas]

Description

There seems to be an issue with the latest Psi4 release on conda. As a result, all checks fail on GitHub. Switching to the previous release seems to fix the problem. This is a temporary solution and once the Psi4 issue is resolved, we can switch to its latest version again.

I had to do some additional modifications to the workflows and environment.yml file. Eventually, we can modify the installation instructions by using the yml file to create the qforte environment and install all dependencies.

All checks on GitHub have successfully passed!
