Update plotly.js version to 1.47.1 in plotly mimetype renderer

[jonmmease]

Closes https://github.com/Microsoft/vscode-python/issues/4953

• Update @nteract/transform-plotly to 5.0.0
• Add @nteract/plotly dependency to directly control minimum plotly.js version. Updates to plotly.js 1.47.1.

With these changes, recent plotly.js features, like themes, are now supported in VSCode 🎉

I can add a news entry if you'd like. I wasn't sure if you include dependency updates in the release notes.
