Replace specific version tags into `latest` tags

[znarfm]

GitHub releases URLs point to a specific version of an application, not the latest release. Changed the URL to point to the latest releases.

Previous URL like https://github.com/author/project/releases/download/v3.0.0/filename are changed into https://github.com/author/project/releases/latest
