Update Django server-side adapter link

[girardinsamuel]

Hi !

I took over the Django Inertia.js adapter as the previous one was not maintained anymore by Andres Vargas.

I am opening this PR to update the link on the community adapters page.

Is this okay with you ?

Thanks 🙏

Hi there ! I don't know if you had time to look at this ? It's just an update of the Django adapter link to the new GitHub repository 😉.

Thank you !
