It's official Debian policy now, believe it or not.
python 2.x is /usr/bin/python2.
python 3.x is /usr/bin/python3.

If the user really wants /usr/bin/python the user should install
python-is-python2 or python-is-python3. And these two packages conflict
with each other.

I'm not familiar with jupyter and I'm not using it.

What I do know is:
a) /usr/bin/python was python 2.x in Debian 10.
b) Python 2.x and python 3.x modules are not compatible nor they are
interchangeable.

Judging from [1], you're required to reinstall all these "jupyter
kernels", because what you have was installed for python2, but what you
need is to install them for python3.

But then again, I could be wrong. Sorry, cannot help you further.
