#1726: Gradle updates not found by GradleUrlUpdater

[SDallmann]

This PR fixes #1726

Implemented changes:

• Refactored GithubUrlUpdater to GithubUrlTagUpdater.
• Added classes GithubRelease and GithubReleases that work like GithubTag and GithubTags respectively, but handle references by @JsonProperty("tag_name") instead of @JsonProperty("ref").
• Added GithubUrlReleaseUpdater that handles Github URLs by release instead of tag.
• Adapted GradleUrlUpdater to get URLs using the newly implemented GithubUrlReleaseUpdater.
• Added tests for GithubRelease and GithubReleases
