Declarations, parameters missing in jazzy documentation

[1ec5]

The published jazzy documentation only contains abstracts, no declarations or parameter listings. As a result, permalinks to individual methods are also broken, and overloaded methods are difficult to distinguish from each other.

Additionally, document.sh produces a litany of warnings along the lines of:

`route` has no USR. First make sure all modules used in your project have been imported. If all used modules are imported, please report this problem by filing an issue at https://github.com/realm/jazzy/issues along with your Xcode project. If this token is declared in an `#if` block, please ignore this message.
`directions` has no USR. First make sure all modules used in your project have been imported. If all used modules are imported, please report this problem by filing an issue at https://github.com/realm/jazzy/issues along with your Xcode project.

This is a regression of #1795 that would be caught by #2078. It reproduces in the documentation for v1.0.0-alpha.1 but not for v0.38.2. I’m pretty sure this is fallout from #2275 that would be fixed by renaming MapboxCoreNavigation/Route.swift to something else that doesn’t conflict with MapboxNavigation/Route.swift.
