fix: Product prices showing as $NaN.undefined on the customer product grid

Resolves #4467
Impact: minor
Type: bugfix

Closing #4484 in favor of this PR.

Issue

When a Product is made visible and published without any Variant, Catalog customer gets price range as $NaN.undefined - $-NaN.undefined

Solution

Add a check in the product catalog publication that makes sure a product has visible variants on it before allowing it to be published to the Catalog.

Testing

• Start the app
• Login as an admin
• Create a product, and make the top level product visible, but DO NOT make the variant visible
• As an admin, see this product is visible to you on the grid (necessary for editing purposes)
• Log out, and see as a customer, this product is not visible to you

@kieckhafer Looks good. There are some failing tests, probably just need to update the test data / factory to be valid products. Also, if you're not intentionally updating package-lock, you should remove it. I think those are just the changes that it automatically makes back and forth depending on where npm install is being run.

@aldeed ready for another look
