@types/node-fetch@3.0.3 (latest) does not include an index.d.ts and "typings" is null in package.json

Description

Using node-fetch 2.x with typescript not possible with latest @types/node-fetch@3.0.3 because package does not contain an index.d.ts and in the package.json “typings” is set to null.

Now I understand that this may be a deliberate choice as node-fetch@3.x does contain its types, however there are no instructions for consumers of 2.x on what to do. If the omission of the typings is intentional on @types/node-fetch@3.x then an additional section in the 2.x branch documentation indicating that TypeScript developers using node-fetch@2.x should specifically install @types/node-fetch@2.5.12.

Reproduction

Steps to reproduce the behavior:

1. Create a default TypeScript environment.
2. Run npm i node-fetch@2.5.12.
3. Run npm i --save-dev @types/node-fetch.
4. Put import fetch from 'node-fetch' at the top of your index.ts file.
5. Run npx tsc.
6. Build fails because

Could not find a declaration file for module 'node-fetch'. 'C:/Users/Foo/Bar/node_modules/node-fetch/lib/index.js' implicitly has an 'any' type.
  Try `npm i --save-dev @types/node-fetch` if it exists or add a new declaration (.d.ts) file containing `declare module 'node-fetch';`

Expected behaviour

The module builds successfully.

Suggestions

Option 1

Add the typings back to @types/node-fetch and instruct TypeScript consumers of node-fetch@3.x to not install @types/node-fetch as that is redundant.

Option 2

Add a section in the README.md of the 2.x branch for TypeScript consumers of node-fetch@2.x to install @types/node-fetch@2.5.12

Edit: Also update the typescript section of node-fetch@3.x which instructs the consumers of node-fetch to install @types/node-fetch as that doesn’t work;

For older versions please use the type definitions from DefinitelyTyped:

npm install --save-dev @types/node-fetch

software	version
node-fetch	2.5.12
node	14.17.5
npm	6.14.14
Operating System	Windows 10

+1, this is really frustrating… any work being done on this?

As a work around in the short term you can have the following in your package.json.

{
  "dependencies": {
    "..."
    "node-fetch": "^2.6.5"
    "..."
  },
  "devDependencies": {
    "..."
    "@types/node-fetch": "^2.5.12"
    "..."
  }
}

This issue is more in the lines of either fixing @types/node-fetch@3.x or changing the documentation to specify that to use node-fetch@2.x in ts, @types/node-fetch@2.5.12 must be used.
