Django 3.1.8 fixes a security issue with severity “low” and a bug in 3.1.7.

## CVE-2021-28658: Potential directory-traversal via uploaded files

`MultiPartParser` allowed directory-traversal via uploaded files with suitably crafted file names.

Built-in upload handlers were not affected by this vulnerability.
