Fix/4.4 doc upload directories

The issue in test pipeline is caused by the test directory. The doc is properly uploaded. The purpose of this MR is to fix the wrong overwrite of doc between multiple versions of the SDK, and to clarify the version in the directory name (4.3 directory will contain doc for the last patch of 4.3). The choice of keeping only last patch's doc for a given minor version was made to save disk space and to avoid redundancy.
