Potential improvement in tutorial files

[Infamous003]

The following markdown files:

1-serialization.md
2-requests-and-response.md
3-class-based-views.md
4-authentication-and-permissions.md
5-relationships-and-hyperlinked-apis.md
6-viewsets-and-routers.md

Do not have syntax highlighting, which makes it a bit harder to read the code. This will be a super simple fix, just add a code block with python or py

For reference:

If it's okay, I can send a PR fixing this

Are you seeing these files in GitHub? They're meant to be used in the docs: https://www.django-rest-framework.org/tutorial/1-serialization/ where the syntax highlighting is present.

I don't mind adding it to the source file, as long as it doesn't break the docs.

[Infamous003]

Yes, this only happens on GitHub. There is syntax highlighting on the actual docs is working.
The changes are very minor, so it shouldn't break the documentation

[browniebroke]

Sure, feel free to send a PR
