No scheme for monorepo

[rafaelpedretti-toast]

In one project I work on we have two apps on the same repo and the extension cannot find the schemes because the response from xcodebuild -list -json has a different structure:

{
  "workspace" : {
    "name" : string,
    "schemes" : string[]
}

where inside a project it is

{
  "project" : {
    "configurations" : string[],
    "name" : string,
    "schemes" : string[],
    "targets" : string[]
  }
}

It would be nice to support this configuration
