Improve README.md

[DmytroLitvinov]

Hi @cobusc ,

This PR fixs how we are adding into URLconf. Instead of django.conf.urls.url() lets show example with django.urls.path() - the new modern way. Also, url() will be deprecated in Django 4.0.

Also, let's show adding AppConfig as dotted path as it is recommended at Django docs. Otherwise we should add default_app_config variable inside __init__.py file.

@DmytroLitvinov thanks for this. Do you mind updating the example/demo/{settings,urls}.py files to reflect these changes as well, please?

[DmytroLitvinov]

Okay. I will ping about finished changes.

[DmytroLitvinov]

@cobusc , could you please check and provide your feedback?

[cobusc]

@DmytroLitvinov Looks good. Can you bump the version to 1.1.0 in setup.py, please? Then I'll merge and do the release ASAP.

[DmytroLitvinov]

I don't think that we need 1.1.0 version. It is only improvements of docs. No fixes or features.

[cobusc]

@DmytroLitvinov OK, so then I am just going to merge and not make a new release. Are you OK with that?

[DmytroLitvinov]

Sure 👍
