Add kedro-viz to add-ons options

[merelcht]

Description

Kedro Viz should be added to the add-ons options, allowing users to get setup for viz (see #2506 (comment)). This option should make use of the new spaceflights-pandas-viz starter: #2985

When a user selects viz they should get the config/requirements needed to run Kedro viz on their project. This shouldn't include the example pipelines. This will happen in a follow up ticket.

Possible Implementation

This solution is likely going to be the same as for the other add-ons work, leveraging the post-project hooks. Since we'd use the spaceflights-pandas-viz starter and not the regular template, we probably need to copy some of the logic from the post-project hook in the regular template to the starter.

Possible Alternatives
