Issue Description:

This diagnostic is not very good, SwiftPM should suggest the right spelling by comparing against the products which are available and suggesting a likely match if the string edit distance is small enough, similar to what the compiler does.

$ swift build
error: product dependency 'FooBar' not found

The edit distance algorithm as landed in SwiftPM with https://github.com/apple/swift-package-manager/pull/1431

Contributor guide

Research direction
Implement an edit distance algorithm to compare the requested product name against available products and suggest the closest match when the dependency is not found.
