This temporarily disables recreating images containing custom repos.
Changes were marked with "Temporarily disable" and "REMOVE" comments to make the revert easier.
This updates the Repositories and Review step as per [mocks](https://www.sketch.com/s/d7aa6d29-fca0-4283-a846-09cc5fd10612/a/MyEbDz7).
Repositories with the unavailable or invalid status have a popover that allows for further inspection. The time of the last introspection and the counter of failed attempts was added to the popover, together with the "Go to Repositories" button.
On Recreate the payload repositories are checked against "freshly" fetched list of repositories. In case any of the previously checked repositories is no longer available in content sources an Alert is rendered on both Repositories and Review steps. The unavailable repository is checked, but the checkbox is disabled and the information is dashed out. Since the information about the repository is stored in the Repository type, the only information available to be rendered is the baseurl.
Create image button is also disabled when recreating an image with unavailable repositories.
This makes the wizard feel much 'faster' for a better user experience.
The implementation uses RTK Query for prefetching. For most API
requests, prefetching is done when the 'next' button is hovered over on
the previous step.
