v1.0.0

The first release of the plotdown action on the GitHub Marketplace.

plotdown renders the ```plot blocks of Markdown files (Observable Plot specs in JSON) as SVG images, and puts each image right after its block, so the charts show on GitHub, npm and any other place that renders Markdown but no scripts.
