CLI tool adds unnecessary dependencies

[ArtemSBulgakov]

Hello.

I've created a project and run deno run -A -r https://esm.sh init. import_map.json looks like:

{
  "imports": {},
  "scopes": {}
}

Then I add some dependencies deno task esm:add react react-dom. import_map.json looks like:

{
  "imports": {
    "react-dom": "https://esm.sh/v110/*react-dom@18.2.0",
    "react-dom/": "https://esm.sh/v110/*react-dom@18.2.0/",
    "react": "https://esm.sh/v110/react@18.2.0",
    "react/": "https://esm.sh/v110/react@18.2.0/"
  },
  "scopes": {
    "https://esm.sh/v110/": {
      "loose-envify": "https://esm.sh/v110/loose-envify@1.4.0",
      "scheduler": "https://esm.sh/v110/scheduler@0.23.0"
    }
  }
}

Then I update all dependencies deno task esm:update. Now the import_map.json has strange dependencies "react-dom/@18.2" and "react/@18.2":

{
  "imports": {
    "react-dom": "https://esm.sh/v110/*react-dom@18.2.0",
    "react-dom/": "https://esm.sh/v110/*react-dom@18.2.0/",
    "react-dom/@18.2": "https://esm.sh/v110/*react-dom@18.2.0/@18.2",
    "react": "https://esm.sh/v110/react@18.2.0",
    "react/": "https://esm.sh/v110/react@18.2.0/",
    "react/@18.2": "https://esm.sh/v110/react@18.2.0/@18.2"
  },
  "scopes": {
    "https://esm.sh/v110/": {
      "loose-envify": "https://esm.sh/v110/loose-envify@1.4.0",
      "scheduler": "https://esm.sh/v110/scheduler@0.23.0"
    }
  }
}

If I try to run update again deno task esm:update, it adds @18.2 again.

{
  "imports": {
    "react-dom": "https://esm.sh/v110/*react-dom@18.2.0",
    "react-dom/": "https://esm.sh/v110/*react-dom@18.2.0/",
    "react-dom/@18.2": "https://esm.sh/v110/*react-dom@18.2.0/@18.2",
    "react-dom/@18.2@18.2": "https://esm.sh/v110/*react-dom@18.2.0/@18.2@18.2",
    "react": "https://esm.sh/v110/react@18.2.0",
    "react/": "https://esm.sh/v110/react@18.2.0/",
    "react/@18.2": "https://esm.sh/v110/react@18.2.0/@18.2",
    "react/@18.2@18.2": "https://esm.sh/v110/react@18.2.0/@18.2@18.2"
  },
  "scopes": {
    "https://esm.sh/v110/": {
      "loose-envify": "https://esm.sh/v110/loose-envify@1.4.0",
      "scheduler": "https://esm.sh/v110/scheduler@0.23.0"
    }
  }
}
