Merge both "pip install" RUN commands in tox/Dockerfile
Closed
requested to merge generated-differential-D3457-source into generated-differential-D3457-target
as a workaround of dependency glitch (radon wants colorama 0.4.1, twine wants colorama >= 0.4.3).
Doing only one pip install command enforce the newer colorama version.
Migrated from D3457 (view on Phabricator)
