Updated positron and dark-matter style URLs

With basemap Nov-17 update (https://github.com/CartoDB/lbs-services/issues/11) @makella has updated positron and dark-matter styles. Now just like with voyager before there is additional “labels under” version for both styles, which has lighter texts, meant to be used as data background. This is exactly Builder case. To deploy it Builder UI should have changed style IDs in the tile URL templates as following:

• “Positron (Labels below)” - /rastertiles/light_labels_under/ (instead of /light_all)
• “Dark Matter (Labels below)” - /rastertiles/dark_labels_under/ (instead of /dark_all)

Visual result is that the texts will be softer and less visible.

URLs of other style variations, like “light” and “labels on top/default” do not change.

Note that issue - need to change URLs was a really a noise and miscommunication. The root issue was that the the main styles were taken from wrong style - from main style project, not from “_labels_below” variations, as detailed in https://github.com/CartoDB/mobile-tileserver-mbtiles/issues/27

So solution after discussions: a) I will redirect dark_all and light_all to dark_labels_below and light_labels_below in CDN. This is how it was originally meant to be really, but accidentally _labels_below was published as separate style name. Quick technical fix is to do it in CDN/Fastly, but I need to test it carefully on Monday before touching live configs. b) this will be transparent to end-users and Builder, so no changes needed there. We keep light_all and dark_all as URLs. All maps will just see “dimmed out” labels, once CDN cache will be cleared: on next Monday, or latest Tuesday early morning EU time, and we hope it is not big disturbance to them. Much bigger sudden visual change happened today already anyway.

Essentially no fix under this issue in builder needed, so closing this issue here.
