Update zoning hyperlinks for sections of DCP website

[hannahkates]

Paul Power noticed that the link in Zola for C3 or C3A from a searched tax lot result pane provides a broken link. Instead of going to https://www1.nyc.gov/site/planning/zoning/districts-tools/c3-c3a.page it uses the following broken link https://www1.nyc.gov/site/planning/zoning/districts-tools/c3.page.

Code is here: https://github.com/NYCPlanning/labs-zola/blob/develop/app/models/map-features/lot.js#L532-L544

It looks like this works for the regular C3 view.

I can see if there's some redundancy in the lookup logic...

Ideally, the tax lot model would have a reference to the appropriate zoning district model...

Doing some archeological work: looks like we added some logic to the zoning district view to handle the idiosyncratic URL scheme of DCP zoning district pages, see this commit.

There are further examples of this: 889cd2d

We should probably have a lookup for these things, with sane defaults... going to work on that.
