Issue description

Python 3.10 is shown as python_version = "3.1" in Pipfile and Pipfile.lock

        "requires": {
            "python_version": "3.1"
        },

Expected result

python_version = "3.10"

Steps to replicate

• On a fresh macOS 10.14.6, installed and activated Python 3.10.0a0 (using pyenv)

brew install pyenv

echo -e 'export LC_ALL=en_US.UTF-8\nexport LANG=en_US.UTF-8' >> ~/.bash_profile
echo -e 'export PIPENV_VENV_IN_PROJECT=1\nexport PYENV_ROOT=$HOME/.pyenv\nexport PIPENV_PYTHON=$PYENV_ROOT/shims/python\n' >> ~/.bash_profile
echo -e 'if command -v pyenv 1>/dev/null 2>&1; then\n  eval "$(pyenv init -)"\nfi' >> ~/.bash_profile

# in new shell
pyenv install 3.10-dev
pyenv global 3.10-dev

• installed latest pipenv and installed the requests package:

pip install git+https://github.com/pypa/pipenv.git
mkdir test1 && cd test1
pipenv install requests
pipenv shell

• then checked the Pipfiles
