Add stub for Django sprint.

[rodrigogiraoserrao]

Added info about the Django sprint to the website.

Hi @thibaudcolas, I spoke with Sarah who told me you'd be up for being the contact person on this sprint.
If you'd be so kind as to take a look at the information I filled in the file src/content/sprints/django.md and edit/let me know what to change, I'd really appreciate it.

Things you are likely to want to change:

• number of people you'll be able to accomodate during the sprint (currently set to TBA)
• the Python level required/expected
• the links about the project (I found a generic docs page about contributing; I'm not sure if you'd rather link to something else more specific)
• the description about the sprint, which may contain info about the specific types of issues you're looking to sprint on

Thank you for your time.
