Install the `llnl-scraper` package from PyPI

[mcdonnnj]

💡 Summary

We should update the pipenv configuration in this project to install the llnl-scraper package from PyPI instead of LLNL/scraper.

Motivation and context

With #147 we (will) switch to installing the llnl-scraper package from the LLNL/scraper repository to get necessary changes. However, it would be preferable to install a minimum version from PyPI instead. Once a new version is released on PyPI with the necessary changes we should switch the dependency to that version as a minimum bound and install from PyPI as normal.

Implementation notes

Once the Pipfile is updated we need to update the Pipfile.lock lock file.

Acceptance criteria
