redundant import statement in Part 1

[martin-martin]

Hello! Thanks for the great tutorial.

I've found a redundant import statement in a section of Pt.1 that could be removed:

from rest_framework.renderers import JSONRenderer

Thanks, for less typing effort for future learners : )

Happy also to fix it and do a PR if that would help - just not sure where the page is built from.

Thanks. I checked this out and it is indeed redundant. I submitted this PR
