Package size over limit

[afcode123]

Context

I haven't deployed or built my zappa project in a while and now that I tried to deploy it yesterday the package size was three times larger than before (before: 33MB, and now 91MB), even though I had not made any changes to the project. I am deploying the project with bitbucket pipelines. The only change was that previously I was using virtualenv<=20.7.2 and now I used 20.10.0 so if I change the pipeline's virtualenv install to
pip install virtualenv==20.7.2 everything works correctly again.
I am thinking that it may be because zappa includes .virtualenv folder, since the package contains packages such as panda and numpy which are not in my requirements file.

using image: python:3.7.3
My pipeline looks the following:

pipelines:
  custom:
    dev:
      - step:
          deployment: Dev
          caches:
            - pip
          script: 
            - pip install virtualenv
            - virtualenv --python=python3 env
            - source env/bin/activate
            - pip install -r requirements.txt
            - zappa update dev

Expected Behavior

Serverless package should be a lot smaller and not contain packages from .virtualenv/

Actual Behavior

Serverless package inlcudes packages that are not in requirements file such as panda and numpy. (Maybe because of virtualenv is included?). Did not happen when using virtualenv==20.7.2 but happens in 20.10.0

Possible Fix

Your Environment

• Zappa version used:-0.52.0 but happens also in 0.54.1
• Operating System and Python version: image: python:3.7.3 in bitbucket pipelines
• Your zappa_settings.json:
