`rasa init` breaks on Linux when you try to train a model in 3.0.0rc01

I just installed Rasa on a new gitpod instance. You can see the versions below.

> python -m rasa --version
Rasa Version      :         3.0.0rc1
Minimum Compatible Version: 2.8.9
Rasa SDK Version  :         3.0.0rc1
Rasa X Version    :         None
Python Version    :         3.7.12
Operating System  :         Linux-5.4.0-1051-gke-x86_64-with-debian-11.0
Python Path       :         /usr/local/bin/python

When I now run rasa init here’s what I see;

> python -m rasa init

Seems like a Tensorflow issue.

> python -m pip freeze | grep tensor
tensorflow==2.6.1
tensorflow-addons==0.14.0
tensorflow-estimator==2.6.0
tensorflow-text==2.6.0

I tried downgrading to tensorflow 2.6.0, but to no avail.

Adding this slack comment for posterity:

So I think this problem is specifically related to the fact that we are updating rasa from inside and old docker container. It’s also an error from tensorflow, as just running import tensorflow from within a python interpreter causes the error to be thrown… I’m still not exactly sure what is causing it as it’s hard to replicate outside of that one prebuilt gitpod container. I have created a fork of the repo where the docker file explicitly installs 3.0.0rc3 and everything works ok - so it’s not an issue with Rasa 3.0.0 on Linux per say. I think my suggestion would be to rebuild the prebuild gitpod container once we release 3.0.0.

I just tried running it on gitpod with rc3. Still persists.
