Lineage display for multiple runs

[ciyer]

Motivation

If a file has multiple versions in the repo, we want to be able to show lineage of all the versions simultaneously. We should use timestamps (and, in particular, not commit hashes) to distinguish between versions of a file.

Proposal

The simplest case is when all versions were generated by the same workflow. For example,

https://dev.renku.ch/projects/cramakri/flights-tutorial/files/lineage/notebooks/01-CountFlights.ipynb

For this, I propose displaying the lineage like this:

We can also show commit hashes to make it easy to check out a particular version.

The Lineage feature won't be further expanded since it won't be part of the new version of the Renkulab platform (more info on Renku 2.0).
I'm closing this issue. Feel free to open a new one if you think there are still reasons to consider a similar functionality.
