skypeforlinux: 8.28.0.41 -> 8.32.0.44 (#48391)

* skypeforlinux: 8.28.0.41 -> 8.32.0.44

Fixes 404 on https://repo.skype.com/deb/pool/main/s/skypeforlinux/skypeforlinux_8.28.0.41_amd64.deb, as only [more recent versions](https://repo.skype.com/deb/pool/main/s/skypeforlinux/) are still available, as previously noted at #31047. Avoiding `x.y.76.z` releases as per the comment.

* update sha256

(cherry picked from commit 72128fc)
