Description

Closes #351
Publishes a new version of Storybook to GitHub Pages every time commits are pushed to dev.

.github/workflows/storybook-publish.yml: The new workflow file dedicated to the publishing.
.github/workflows/storybook-tests.yml: Renamed from storybook.yml for consistency and clarity.
README.md: Added a reference to the published Storybook in the landing page of the repository.

Storybook is published in enbloc-org.github.io/kindly/storybook instead of enbloc-org.github.io/kindly. This makes the URL more explicit and leaves the base URL available if there's the need to deploy something else there in the future.
I thought it would be a good idea to reference the published Storybook in the README.md file. Please review the location and message.
⚠️ Manual step needed! An admin will need to tweak the Pages settings of the repository, making sure that the "Source" is "GitHub Actions" (in the "Build and deployment" section).
