Export keepass could also export folder hierarchy

[mathieumd]

Describe the bug:
passbolt export keepass works well, it's a very useful feature.

But the generated kdbx database contains all passwords under the root, without the original folder hierarchy. It's actually not really a big problem; but if it were possible to retrieve the folder hierarchy too, it would be nice.

Passbolt Server Version (please complete the following information):

• Edition: Cloud
• Version 4.8.0-1

go-passbolt-cli Version (please complete the following information):

• OS: Debian
• Version 0.3.1
