DOCS: Inaccuracy on README due to the old version on pypi

[simotrone]

The following part of the readme needs fix.

Set up the virtual enviroment and install dependencies

cd app
python3 -m venv env
source env/bin/activate
pip install django-daiquiri mysqlclient

The process started with pip install django-daiquiri (downloading from https://pypi.org/project/django-daiquiri/) retrieves an old version of daiquiri (v0.2) with version constraints in the list of related packages causing the installation to fail.

The errors are:

ERROR: django-extensions 3.2.0 has requirement Django>=3.2, but you'll have django 1.11.29 which is incompatible.
ERROR: drf-extensions 0.7.1 has requirement djangorestframework>=3.9.3, but you'll have djangorestframework 3.8.0 which is incompatible.
ERROR: django-filter 22.1 has requirement Django>=3.2, but you'll have django 1.11.29 which is incompatible.
ERROR: django-allauth 0.51.0 has requirement Django>=2.0, but you'll have django 1.11.29 which is incompatible.

As of now, we release daiquiri on PyPI semi-regularly ( current version 0.4.5) which fixes the issue.
