Seen in pair review:

it's more like a frontend display issue. The yup validation is working fine as it is in ArtifactCreation. It's just that the error message is not displayed.

We need to pass down the formik errors to the CustomFileUpload so that it's internal error state is updated on formik error received, and not only on the custom error it checks on his own.

This way user gets a good feedback in the form.

As for the observable creation form, it's a lot more work as this is used for all types of observables, without yup validation... and backend errors are not always understandable. See #5454

I just added a createArtifact test. I would appreciate a review of this part if possible.
