Add anchors to django code style docs

[Stuart Axon]

It would be good if there were anchors on all the subsections on here.
​https://docs.djangoproject.com/en/dev/internals/contributing/writing-code/coding-style/

Currently I can link to
​https://docs.djangoproject.com/en/dev/internals/contributing/writing-code/coding-style/#model-style

But I can't further link to the item about that starts
"The order of model inner classes and standard methods should be as follows (noting that these are not all required):"

It would be useful for humans, but and possibly linters.

Hi Stuart.

That whole model style section fits virtually within a single screen. TBH I looked at in portrait first, where in fact it does. At that point, the re-write to add additional anchor points for each list item is not worth the additional linking accuracy. Just link to #model-style.

All the sections are pretty short. Python style is the longest, but even that is less than two screens.

As such I have to say it's not worth the effort to implement, and subsequent work for the translation teams.
Thanks.
