Extend the tox<4 pinning for unmaintained branches also

Tox was pinned < version 4 for all stable branches <=zed.
With new branch namespace, those stable branches moving to
unmaintained/* name[1] and endup using the latest tox version
and fail[2]. To fix that, we need to extend the tox pin for
those unmaintianed branches also.

Currently only unmaintained/yoga is proposed but soon or in
future all branches from victoria to zed are moving to
unmaintained/ so pinning tox for those branches also.
