Django 1.11.21 fixes a security issue in 1.11.20.

## CVE-2019-12308: AdminURLFieldWidget XSS

The clickable "Current URL" link generated by `AdminURLFieldWidget` displayed the provided value without validating it as a safe URL. Thus, an unvalidated value stored in the database, or a value provided as a URL query parameter payload, could result in an clickable JavaScript link.

`AdminURLFieldWidget` now validates the provided value using `URLValidator` before displaying the clickable link. You may customize the validator by passing a `validator_class` kwarg to `AdminURLFieldWidget.__init__()`, e.g. when using `formfield_overrides`.
