Add wheel to avoid warnings

[moltar]

Wondering if the solution outlined here can be added to the bench image?

bench image is for easy development and builds, we can add anything that is needed. Just send PR.

EDIT:
I was thinking of building worker image using same frappe/bench as we're doing for nginx image.

Can you add it here and check if it solves the issue?

frappe_docker/images/bench/Dockerfile

Lines 101 to 102 in 7b5eac5

	&& PYENV_VERSION=$PYTHON_VERSION_V13 pip install --no-cache-dir virtualenv \
	&& PYENV_VERSION=$PYTHON_VERSION pip install --no-cache-dir virtualenv \

If that works we'll add it in image.

will be fixed in #1032 using upstream bench which added wheel installation as part of init
