Docs: Shortest Path and Single Source Shortest Path refer to the same algorithm

[Mona144]

I noticed that at one point in the docs both Shortest Path and Single Source Shortest Path refer to the same algorithm

Shortest Path (algo.shortestPath)
Single Source Shortest Path (algo.shortestPath)

I also noticed that this is not the case here, which I assume is correct

Shortest Path (algo.shortestPath)
Single Source Shortest Path (algo.shortestPath.deltastepping)

Thanks @Mona144 this is fixed, and the updated docs will be published soon.
