Update plotly_artifacts to plotly.js v3.3.0

[abcdvvvv]

Hi, thanks a lot for maintaining PlotlyLight.jl!

Currently the plotly_artifacts artifact points to

PlotlyLight.jl/Artifacts.toml

Line 6 in c7f7035

url = "https://gist.github.com/joshday/4aa57a979cf93d1b7a941282bb4dc5f2/raw/c89283c56ed8771a64f0c0e2d68f701c2ee65005.tar.gz"

Inside that artifact, version.txt is v3.0.1, so PlotlyLight loads plotly.js v3.0.1.

The latest plotly.js is v3.3.0. Could you update this artifact to the latest version?

Thanks!
