I found this for the robotframework_ls

{ 
  "robotframework_ls" : "https://github.com/robocorp/robotframework-lsp/tree/master/robotframework-ls/package.json"

Thanks @donus3. I'll no longer maintain this gist as this has been moved to the package spec in https://github.com/mason-org/mason-registry instead. FYI @tamago324 @folke, you might want to source this elsewhere.
