Update packaging metadata and version compatibility.

Review Request #12220 — Created March 30, 2022 and submitted — Latest diff uploaded


Django Evolution


The Django Evolution documentation and package metadata now specifies
compatibility with every version of Django from 1.6 through 4.0.

The package metadata has also been updated to list us as the author. The
original author, Ben Khoo, remains in AUTHORS as the original author.

This change is being made for a couple reasons.

1) Likely, Ben probably wouldn't want anyone to reach out to him for
support, given how much has changed since he worked on it.

2) Related, almost all of Django Evolution has been rewritten since
those days by us.

This will guarantee that we're responsible for any reports from end
users going forward.

Built the package and saw the new metadata.
