Return schema in VNFPackageManagement shouldn't be nested in properties

In branches 2.8.1, 2.7.1-maintenance , 2.6.1-maintenance, the return schema in 3 operations is wrongfully nested compared to the spec. This:

schema:
  properties:
    VnfPkgInfoModifications:
      $ref: "definitions/SOL005VNFPackageManagement_def.yaml#/definitions/VnfPkgInfoModifications"

Should be like this:

schema:
  $ref: "definitions/SOL005VNFPackageManagement_def.yaml#/definitions/VnfPkgInfoModifications"

Here's a patch for it for branch 2.7.1-maintenance:
