Clone content when creating multi-language variation for Knowledge Base

[YiRui_Chua]

Hey team, as per the community thread here, currently:

• When we click on "Create multi-language variation" for KB product, the duplicated content comes out empty.
• This is different from Landing and Website pages, where english (original) content would be copied over to the new language variation.

This is key since it can take a substantial amount of time to reformat the KB. Thank you!
