[8.x](backport #5647) Include python wheel packages when moving downloaded dependencies archives

[mergify]

What does this PR do?

This commit modifies movePackagesToArchive() function to include python wheel packages introduced with commit 701f8b9 .
This solves an issue when packaging docker images using a DROP_PATH env var: prior to this change, the python wheel archives present in DROP_PATH were not moved to <DROP PATH>/archive/<platform> failing to create an image for which the Dockerfile expects to install the python wheel package

Why is it important?

To have a successful docker image creation during unified build processes.
