Swift Package Dependencies Checker

This action process your Package.swift file to detect outdated versions based on your package dependency requirements. Action will fail in case there are outdated dependencies. This can be suppressed by setting the input parameter failWhenOutdated to false. Then use the output parameter outdatedDependencies to know if the action detected any outdated dependencies. By setting isMutating you declare the intention to update Package.resolved (if present). Please note that the action itself does not commit/push changes. The GitHub action is looking in the current directory (.) for the package manifest but you can pass a different path with input parameter directory. Helpful for Monorepos where the Package.swift may not be at the root of the project. When setting isMutating the tool SwiftPackageIndex/ReleaseNotes is used to return release notes URLs for detected, necessary updates.
