Add storybook and tests ICSHWI-9199

This merge requests adds Storybook (https://storybook.js.org/) to our application.

Storybook provides a way for us to visually document our components and the various states they can be in. This is very helpful when discussing visual changes. It also provides a method for us to set up components for testing.

In this merge request:

• Dependencies and configuration are added for storybook
• Storybook stories are added for the table components in our application
• Cypress component tests are added which make use of the table component stories
• Gitlab-CI is updated to build the storybook static web page and store it as an artifact

To check out the storybook, you can download and extract the artifact from the "build-storybook" job in the pipeline and open index.html. You should see something like this:
