The term “url” is overloaded in services, to refer to the Shields route and also the API URL. Calling the Shields URL a “route” is on the whole more descriptive, and makes it clearer and more obvious which one of these we’re talking about. It’s a small thing, though seems like an improvement.
We have a few functions called `buildUrl`. I’ve renamed them to `buildRoute` when they refer to routes, and left them as `buildUrl` when they refer to API URLs.
I included a minor style tweak and some formatting cleanup in `TUTORIAL.md`.
Continuing the work from #2234, this creates additional, empty LegacyServices to hold the badge examples for conda and cocoapods. It's an approach we could take to finish emptying out all-badge-examples while the refactoring continues.
On the website badge, even the first URL path component is variable. I didn't think it could be moved, but it can!
