There was a disabled Details test in CreateImageWizard.test.tsx, this moves the test to Details.test.tsx, updates it and enables it again.
The re-enabled tests are checking maximum length of image name and description.
This cleans up OpenSCAP test file, utilising helper functions we already have and updating names of test and describe blocks to be consistent throughout the test files.
This add tests to check whether the Review and finish button works properly, sending user to the Details step. And whether it's disabled when the state is invalid.
This moves `selectCustomRepo` to `wizardTestUtils.tsx`
Since the function was originally imported into `Packages.test.tsx` from `CreateImageWizard.content.test.tsx` the entire content suite was re-run under Packages suite each time. This solves the issue.
