Update ruby4.0

[aaccensi]

Context

As part of modernizing and unifying our Ruby on Rails stack we are bumping Ruby to 4.0.2, the latest stable version .

Implemented changes

Upgrade Ruby to 4.0.2 on all 5 repos (etengine, etmodel, etsource, etlocal, my-etm)

• Made sure all repos are aligned using latest Bundler 4.0.6
• Dockerfiles and version files updated
• Specific gem bumps/fixes

Additional we implemented a fix in clone_dataset method, that in earlier versions of Ruby was kept hidden.
The cause of this issue is that dataset.data contains the Lifecycle object, which holds @graph, which holds @dataset (a circular reference). The dataset also contains Proc objects stored via dataset_lazy_set. Under Ruby 4.0, Marshal.dump raises SystemStackError on this combination instead of TypeError, bypassing the rescue fallback in deep_clone and crashing the request (This being exposed after the Ruby 4.0 update).

Note: rescuing SystemStackError along with TypeError in deep_clone would also fix the crash by keeping it hidden from us like before and falling back to obj.deep_dup. But from what could find, this actually produces a shallow copy of the dataset, not a deep clone, I guess a deep copy is not needed if this works but by using Marshal I assume that was not the original intention.
