fix(product-duplicator): Add source variant customFields to duplicated variant

[mschipperheyn]

Description

Product duplicator now copies variant customFields. Fixes #3202

Breaking changes

• This will start copying variant related customFields when you use the product duplicator with includeVariants: true. This could potentially cause unexpected side effects, if your code previously assumed those customFields were not copied.

There seems to be a problem with the CLA bot - it is having trouble updating the JSON file. This might be due to other changes to that file since you branched off master last week. Would you mind merging master into your branch and then pushing the result to this PR?
