More issues in release workflow

[glx22]

Adding --verbose to pip command helped to find the manylinux issue, keeping it will not hurt :)
Manylinux issue was

 fatal: detected dubious ownership in repository at '/github/workspace'
 To add an exception for this directory, call:

 	git config --global --add safe.directory /github/workspace
 fatal: detected dubious ownership in repository at '/github/workspace'
 To add an exception for this directory, call:

 	git config --global --add safe.directory /github/workspace
 Git checkout found but cannot determine its version. Error:  Command '['git', '-C', '/github/workspace', 'diff-index', 'HEAD']' returned non-zero exit status 128.

So no surprised it decided to use 0.0.0 as version.

While fixing stuff set-output is deprecated.
Will also need to replace actions/upload-release-asset as it's not maintained and uses deprecated node.js (but no hurry with our not so frequent releases)
