Restore some stories tabs

[RichDom2185]

Description

• Restore data visualiser, HTML display, and stepper tabs
• Fix incorrect stories reducer (it was missing the hotfix from hotfix: stepper #2305)

There are still some bugs remaining, but nothing too major:

• The stepper runs the code chunk as if it were a fresh program, i.e. without any prepends. Thus we need to ensure that everything is defined in the same code block.
  • e.g. we can't have function definitions in Block 1, and their function calls in Block 2, and run the stepper from Block 2.
• _(only affects authors, not viewers) Updating chapters/variants is not being propagated correctly into the component lifecycle. If you change a code block's environment from Source 4 to Source 2 (or something that does not support the stepper to something that does), you will need to save the file and refresh the page in the browser for the stepper to work.
