Disable cell id generation while working on jupyter notebooks locally

Issue context

While working on some notebooks like QFT workbook with jupyter locally, it generates cell ids to all type of cells(code, markdown, etc). This is on not a problem if someone is running a kata locally. However, its extremely frustrating for people who want to contribute to Quantum Katas repo. As a mitigation, we might want to use "git add -patch" or edit the JSON object directly in VSCode for extremely small changes. But it does not scale well if someone wants to add a section/tasks to the notebooks

Issue discovery

I recently moved to a new device and noticed the generation of "id" field for QFT workbook when I raised PR #819 . To avoid the noise in my PR, I opened the workbook with VSCode in json format and edited the json directly instead of doing it from jupyter locally. Later, I discovered that this issue was not happening in QFT kata. So, I investigated further on this and found that nbformat minor versions are different(4.2 in QFT kata, 4.5 in QFT workbook)

Problem reason

Nbformat version 4.5 introduced a new field cell id to be added to all type of cells(code, markdown, etc).

Potential Fix

Downgrade nbformat version to 4.2/4.4
