Feature: Export all NocoDocs

Please confirm that the feature request does not already exist

• I confirm there is no existing issue for this feature request.

Use case

NocoDocs can be exported only one-by-one. https://nocodb.com/docs/product/docs/export-document#how-to-export If I start using NocoDocs as knowledge base and create many docs inside, it will get very difficult to export them all. So if I would need to transfer my data somewhere else, I am stuck.

It would be useful to be able to export all NocoDocs at once.

Suggested solution

Maybe ability to select multiple top-level NocoDocs and button "export including child documents". This way I would just select the few top level ones and could export them all at once.
