This PR is waiting for the redwood release. For now, it is only working for the quince release. It's failing on master because the master branch of edx-platform is broken due to a dependency version issue. For redwood, the tutor is not yet ready (release notes for the latest major release v17.0.0).

Removed this code of installing dev dependencies as this resulted in a conflict with tutor edx-platform dependencies. I believe all the required dev dependencies are already installed in the tutor edx-platform container.

Why did this block get deleted? We can legitimately get rid of black and isort, but the rest should be retained.

[Anas12091101]

I thought we were only using these dependencies in the CI, therefore deleted them, will re-add them in the next commit.

Aside from the deletion of the dev dependencies, the rest of the changes here look good.
