Change order in the readme

[korikuzma]

It says "once installed as described above" but this venv and the directory layout venv/<version> is created in the makefile. The makefile step make devready is below in Installing for development. Maybe before the pip install above we should add a step about creating a virtual environment with python3.10 -m venv venv/3.10, or add it to this section.

Should we also put a note that Python 3.10 must be installed? The makefile won't run otherwise.

(I have mixed opinions on tying the makefile to a python version)
