Also detect Gradle projects that only have a setting.gradle(.kts) file in the root

[jjohannes]

This is a Gradle-related issue concerning https://github.com/snyk/cli and it's interaction with Gradle and snyk-gradle-plugin. As I found no information about how to report an issue for cli directly, I am reporting it here instead. Please feel free to close this and move it to the appropriate channel.

The DETECTABLE_FILES files list here should include settings.gradle and settings.gradle.kts:
https://github.com/snyk/cli/blob/main/src/lib/detect.ts#L21-L22

One of these files is sufficient for a project to be a "Gradle project". There is no need to have a build.gradle(.kts) in the project root. Moder multi-project setups often do not have it and only have build.gradle(.kts) files in subfolders.
