fix(skore): Don't use widget for summary repr in IPython terminal

[FrancoisPgm]

Fixes #2070

Add a check to verify if we're in a IPython terminal. If it is the case, use DataFrame's _repr_html_ instead of Summary's widget.

I mistakenly re-added the 3 commits that were already in my first PR. I'll open another one with only the new commits.
