Documentation for `NIOFileSystem` can not be viewed

The [documentation page for `NIOFileSystem`](https://swiftpackageindex.com/apple/swift-nio/2.92.1/documentation/NIOFileSystem) is empty.

The last page that actually displays anything seems to be [the one for version 2.86.1](https://swiftpackageindex.com/apple/swift-nio/2.86.1/documentation/NIOFileSystem). Maybe #3380 broke something?
