Issue is get_pip.py is moved to pip 21.1 (https://github.com/pypa/get-pip/commits/main) which is not compatible with 3.6.
Issue of pip itself is fixed as part of 21.1.1 in pip community (pypa/pip#9835).
However get-pip.py is still not updated to latest pip. Also get.pip.py does not support python 3.6 version explicitly (pypa/get-pip#88)
Step 15/29 : RUN curl https://bootstrap.pypa.io/get-pip.py | python3.6

ImportError: cannot import name 'NoReturn'
The command '/bin/sh -c curl https://bootstrap.pypa.io/get-pip.py | python3.6' returned a non-zero code: 1
How I did:
Got the file from https://github.com/pypa/get-pip/tree/21.0 and added to the buildimage
pin pip to the previous release 21.0.1. (Similar is done in other public repos eg: grpc/grpc-java#8115)
