PodUpload.upload() does not preserve folder structure anymore when uploading a directory

[msinger-dev]

Describe the bug

Fabric8 does not preserve the folder structure when uploading directories and just puts everything in the root directory. So files that should be uploaded to /root/path/to/sub/folder will be uploaded to /root instead.

Fabric8 Kubernetes Client version

6.6.2

Steps to reproduce

1.) Call client.getPodResource(<pod>).inContainer(<>).dir(<dest>).upload(<sourcePath>); with a directory that has nested subfolders with files in it.
2. ) All files will be uploaded to the root folder and not in the nested subfolder as expected.

Expected behavior

Folder structures are also represented in the destination again, when uploading a directory with PodUpload.upload()
