Fix docker port

[ScriptAutomate]

Port 5000 should be 5005 due to the configurations set in this repo, which can easily be seen with grep -R 5005 from the repo root:

# grep -R 5005
gunicorn-cfg.py:bind = '0.0.0.0:5005'
docker-compose.yml:      - "5005:5005"
nginx/appseed-app.conf:        proxy_pass http://localhost:5005/;
app/base/static/assets/scss/material-dashboard/variables/_colors.scss:$pink-a400: #f50057 !default;
Dockerfile:EXPOSE 5005

The following all reference port 5005:

• docker-compose
• Dockerfile
• gunicorn
• nginx/appseed-app.conf

Listing port 5000 in the readme is incorrect, it should be 5005.

Attempting a similar grep -R 5000 shows:

# grep -R 5000
README.md:$ # --port=5000    - specify the app port (default 5000)  
README.md:$ flask run --host=0.0.0.0 --port=5000
README.md:$ # Access the dashboard in browser: http://127.0.0.1:5000/
README.md:Visit `http://localhost:5000` in your browser. The app should be up & running.
app/base/static/assets/scss/material-dashboard/variables/_colors.scss:$red-a700: #d50000 !default;
app/base/static/assets/js/plugins/bootstrap-notify.js:    delay: 5000,

Those are all unrelated to a port listening or exposed at port 5000, other than the incorrect README directions.
