Setting `non-relative` for `importModuleSpecifier` fails when package links itself

[o-alexandrov]

Does this issue occur when all extensions are disabled?: Yes

• VS Code Version: 1.64.2
• OS Version: macOS 12.2.1

Steps to Reproduce:

• for your convenience, here's a minimum repro, but you'd need to use VSCode

Or follow these steps:

1. Use any package manager that allows to link a package
2. Add package.json

{
  "name": "pkg",
  "devDependencies": {
    "pkg": "file:."
  }
}

3. Define a variable in a separate from the testing file (ex. example.ts)
4. Attempt to auto import from the testing file (index.ts) the variable declared in example.ts
5. VSCode fails to auto import using a non-relative path
   • even with typescript.preferences.importModuleSpecifier set as non-relative
   • expectation
     • pkg/src/example
   • current VSCode's behavior
     • ./example
