Unable to build, mermaid package not found

[Hydragyrum]

I am unable to perform a yarn install of this repo, as the @mermaid-js/mermaid seems to not exist on the yarn package repo.

Console log as follows:

Hi!
Try now. At that moment the repo was using an preview version of mermaid from the github package respository. You could setup npm/yarn to use that.

Now after the release it is again using the standard package.

I will add a markdown file explaining how to do this. I will have the preview version at a different path in the future. This has been my forst experiment with sveltejs and I am quite happy with svelte. The stores could probably be setup differently if this was a bigger app but for this purpose it works.

The github package @mermaid-js/mermaid is now relegated to the develop branch for the preview versions of mermaid so this should no longer be an issue.
Thanks for you report.
