README: Fix Django compatibility

[marcelometal]

HI, Semantic versioning says to not introduce breaking change without releasing a new major version.

Given a version number MAJOR.MINOR.PATCH, increment the:

MAJOR version when you make incompatible API changes MINOR version when you add functionality in a backward compatible manner PATCH version when you make backward compatible bug fixes Additional labels for pre-release and build metadata are available as extensions to the MAJOR.MINOR.PATCH format.

Drop Django 4 support in 4.3.0 is a breaking change.

In the future, please change the major version and not the minor version.

The toolbar still supports django 4.2. I don't agree dropping support for release points necessitates bumping the major version. Django's release strategy means you should be able to upgrade from 4.0 to 4.1 to 4.2 relatively easily.

Hi @tim-schilling ,

After updating to 4.3.0:

My local dependencies:

• Django==4.2.11
• django-material==1.11.3

I don't think this is a valid PR given the toolbar supports v4.2, so I'm going to close it.

Regarding the exception, if you'd like help with debugging it, please create a minimal environment that reproduces the problem. As a note, it appears that https://github.com/viewflow/django-material was archived in February and is no longer maintained. The last supported version of Django looks to be v4.1.

Ok, but that bug only occurs when I use django-debug-toolbar 4.3.0

I will try to create a minimal environment that reproduces the problem. But, as I said, installing django-debug-toolbar 4.2.0 there is no error.
