Django Security Releases: 6.1.2, 6.0.9 and 5.2.18

Django issued security releases for the 6.1, 6.0 and 5.2 series, fixing five issues. They include a low-severity denial of service in get_supported_language_variant() and a moderate denial of service from quadratic header parsing in parse_header_parameters().

The other fixes cover a moderate request forgery through spatial lookup byte values, which now requires GDALRaster wrapping and is backward-incompatible, and a moderate privilege abuse in model formsets with editable primary keys. A stronger follow-up fix for the nested geometry collection denial of service is also included. Django recommends upgrading as soon as possible.
