Remove the notebook 5.1 check for large uploads
Remove the notebook 5.1 check for large uploads

In JLab 3, we are using Jupyter Server, which unfortunately advertises its own version as the notebook version (1.2.1, for example). This trips up this notebook version test.

Since we do not support the notebook server for JupyterLab 3, we can eliminate the version check entirely.

Fixes #9601
