Consistent doc deploy and PR preview

[lucyleeow]

🧰 Task

The workflow for previewing docs in PRs via CircleCI and deploying docs are slightly different. Github uses Talleys QT action whereas we install manually in CircleCI. See: #283 (comment) for details

I think it may be a good idea to make them consistent as we would assume that if the docs look fine in CircleCI, they would be fine when deployed (this happened in #283 and #285)

The problem is I'm not sure CircleCI can take github actions as a step, so I don't know if we can use Talley's action there. I will try to investigate.

If we can't take a github actions step, could we replicate it manually?

There is no option to take action directly

Related we build napari differently:

Circle CI installs:

docs/.circleci/config.yml

Line 35 in 1c6155f

python -m pip install -e "napari/[pyside,dev]"

GitHub Actions:

docs/.github/workflows/build_and_deploy.yml

Line 50 in 1c6155f

python -m pip install "napari/[all]"

CircleCI build is using PySide and the GH-Actions build is using PyQt5 (from napari[all]).
