Fix relevant notebooks

[bvarjavand]

1. fix filepaths for uploading notebook
2. with use_https=True we don't need an aws key for downloading notebook
3. clean data uploading by adding to .gitignore

Also, i believe the reason tests fail are because you need to bump nilearn version to 0.7.0 in requirements.txt (this has been changed in the develop branch).
