fix: Fix issue with search index that prevented incremental rebuilds

[jbms]

Fixes #12

[2bndy5]

the build CI could be triggered for only PR opened events since any push also triggers a PR synchronize event (resulting in 2 runs for each commit when a PR is open)

on:
  pull_request:
    types: [opened, reopened]
  push:

Also, IDK if this is a high priority for you, but it seems the pypi token is invalid. I would greatly appreciate using a wheel from the test pypi server. Currently, I've been using a locally copied wheel for my RTD project, and I'd like to avoid that.

I just pushed a PyPI package and added the token (you have to push an initial version manually before you can generate a token).

https://test.pypi.org/project/sphinx-immaterial/

pip install -i https://test.pypi.org/simple/ sphinx-immaterial

there's a space in the url which prevents using it in a requirements.txt file (I have tried using single and double quotes). Without the space, pip gets a 404. Without quotes, git clone errors out.

oh I see you pushed to regular pypi. That works just as well 😃
