Update npm command to support version 9

[andyreagan]

NPM drops support for the bin command in version 9 (ref here), while root is backwards compatible: ref.

@jakevdp I think this should be a pretty simple 1-line fix to merge in?

I just checked the issues tab, and this closes #113 .

AFAICS, the failing CI checks are not due to changes in this PR, but some issues on the CI env/config.

The anaconda distribution can be solved by using nodejs=18.13.0 as a forced dependency.

Anaconda had it auto-updated which later used npm9+ that fails...

Thanks for you PR @andyreagan. As you have noticed, there hasn't been any development in this repo for a while. Since Altair 5.2, the functionality of Altair Saver is now available in Altair via the vl-convert package. Most of the functionality has been available since 5.0, and the main addition in 5.2 was PDF export. See the docs on how to save charts for more details.

We are going to archive this repo, so I'm closing all the open issues and PRs before doing so. Try out the new options for saving charts mentioned above and if you run into issues, please open an issue directly in the altair or vl-convert repo.

Thanks for the very thoughtful follow up here! I'll be using vl-convert in the future :)
