docs of older versions are not accessible

After the update the documentation for previous version is gone.

Following the recommendation to pin the pyscript version this makes a delayed migration hard.

Maybe this is out of scope for the current phase, still it would be convenient.

As a stopgap, you can view the docs from the previous release under their tag on GitHub. Most of the content is in Markdown, so it renders pretty well in the GitHub UI.
