Type dependencies should be pinnable and/or be from same build

[jason0x43]

Type dependencies are not always consistent within a build, and sometimes change over time for a given build of a package. I have mostly seen this problem with react and react-dom, which will sometimes use different type dependencies for the same packages, even when pinned.

This may be related to #234.

For example, in a current project I'm importing build 68 of react and react-dom:

{
  "imports": {
    "react": "https://esm.sh/[email protected]?pin=v68",
    "react-dom": "https://esm.sh/[email protected]?pin=v68"
  }
}

If I run deno info mod.ts for my project, I see the following imports for react:

│ │ │ │ └─┬ https://esm.sh/[email protected]?pin=v68 (172B)
│ │ │ │   ├─┬ https://cdn.esm.sh/v68/@types/[email protected]/index.d.ts (148.34KB)
│ │ │ │   │ ├── https://cdn.esm.sh/v68/@types/[email protected]/global.d.ts (7.01KB)
│ │ │ │   │ ├── https://cdn.esm.sh/v68/@types/[email protected]/index.d.ts (3.58KB)
│ │ │ │   │ ├── https://cdn.esm.sh/v68/@types/[email protected]/tracing.d.ts (4.03KB)
│ │ │ │   │ └── https://cdn.esm.sh/v68/[email protected]/index.d.ts (850.38KB)

And for react-dom:

│ │ └─┬ https://esm.sh/[email protected]/server?pin=v68 (193B)
│ │   ├─┬ https://cdn.esm.sh/v68/@types/[email protected]/server~.d.ts (1.89KB)
│ │   │ └─┬ https://cdn.esm.sh/v73/@types/[email protected]/index.d.ts (148.44KB)
│ │   │   ├── https://cdn.esm.sh/v73/@types/[email protected]/global.d.ts (7.01KB)
│ │   │   ├── https://cdn.esm.sh/v73/[email protected]/index.d.ts (850.38KB)
│ │   │   ├── https://cdn.esm.sh/@types/[email protected]/index.d.ts (3.58KB)
│ │   │   └── https://cdn.esm.sh/@types/[email protected]/tracing.d.ts (4.03KB)

The versions for @types/react are different for the react and react-dom dependencies, causing errors while type checking. Type dependencies can also change when new builds are published, even when a project has pinned dependencies, meaning that a build that works on one machine may break when run on another due to different package versions being downloaded.
