Add more information in the /project endpoint v2

[adpi2]

Currently the programmatic /project endpoint returns:

  artifact: List[String],
  versions: List[String],
  groupId: String,
  artifactId: String,
  version: String

A lot more information could be added in a version 2 of this endpoint:

  website: String, 
  githubUrl: String,
  topics: List[String],
  stars: Int,
  forks: Int,
  contributors: List[String]
  projectDependencies: List[String]
  ...
