jupyter: fixed previewer for jpynb

[alejandromumo]

closes inveniosoftware/invenio-app-rdm#1751

EDIT: it seems that tests were also failing on master previously https://github.com/inveniosoftware/invenio-previewer/runs/5771027111?check_suite_focus=true

LGTM, one comment on the template selection.

Another concern is if we should bump the minimum version of nbconvert (from the current 6.0) to avoid hitting this issue, but it seems like the base template was also present in 6.0 (otherwise the min tests would fail I guess).

Hi @alejandromumo I have the same issue in invenio-rdm 9.1. Just want to know when to release the newer version of invenio-previewer? Now the latest v1.3.6 does not have this fix.

Hello there, I am sorry for the delay.
I created an issue to track this and we will try to release it as soon as possible.
