Consolidating functional connectivity examples: merge 8.4.1 and 8.4.7

[illdopejake]

Some of the current nilearn examples include some redundancy that creates unnecessary burden for test run-times.

An example of this would be 8.4.1 (Group analysis of resting-state fMRI with ICA: CanICA) and 8.4.7 (Dictionary Learning and ICA for doing group analysis of resting-state fMRI), which contain a good deal of redundancy.

The goal here would be to create a single example that combines the non-redundant elements from both 8.4.1 and 8.4.7., and perhaps modifying the didactic structure such that it might better reflect the goals and thought-process of an end user.

As recommended by @KamalakerDadi , would also be useful to merge 8.4.5 (Extracting brain signal from spheres) and 8.4.8 (Extract signals on spheres from an atlas and plot a connectome) into one notebook with both spheres and a full atlas.

So for reference:

• 8.4.1 + 8.4.7
• 8.4.5 + 8.4.8

This looks like it was closed with #2013.

I think #2013 is missing status on whats_new. I was looking for plot_canica_analysis example to work on my PR #1890 and realized lately that it is merged into plot_compare_decomposition. There is no mention of this in whats_new.

Should we open a new PR specifically for that or do you want to handle it in #1890, @KamalakerDadi ?

I think you followed it better than me.

Opened #2183 , if you'd like to review @KamalakerDadi ! 😸
