This reverts commit d9c52ee3

Previously worked on supposition that all version were synched
(i.e. all aidge modules were on 0.3.xx at the same time).
This is not the case. This led to issue like this releas pipeline
https://gitlab.eclipse.org/eclipse/aidge/aidge_quantization/-/pipelines?page=1&scope=all&ref=v0.2.0
where version retrieved for core & backend cpu were 0.2.xx instead of 0.3.xx
