Ensure to include parent folder into archive

[jonesbusy]

Description

Also fix nested folder. Previously only the folder name was taken which was not consistent with Go SDK

For example pushing src/main/java correctly set the title to src/main/java

Absolute path are also kept with original behavior (folder name). Expect they are now correctly packaged

    "layers": [
        {
            "annotations": {
                "io.deis.oras.content.digest": "sha256:13e37d5391939b4f2b1f43a2f0966ec2b02266555e0399d7dd40208a98bb987b",

    ],
