fix: correction to the set resolution docs (#6739)

## What's the problem this PR addresses?
The example in the `set resolution` docs does not work for many
packages.
https://yarnpkg.com/cli/set/resolution#examples

### Issues
Resolves #5979 

### Steps to reproduce:
1. Clone and `cd` to the `yarnpkg/berry` repository
2. Run `yarn set resolution lodash@npm:^4.17.11 4.16.0`
3. Observe the following error
```
yarn set resolution lodash@npm:^4.17.11 4.16.0
➤ YN0000: · Yarn 4.7.0-dev
➤ YN0000: ┌ Resolution step
➤ YN0001: │ Error: [email protected] isn't supported by any available resolver

➤ YN0000: └ Completed

```

## How did you fix it?
The fix is to include npm before the resolved version, `4.16.0` ->
`npm:4.16.0`.
The full command will be `yarn set resolution lodash@npm:^4.17.11
npm:4.16.0`.

### Result
Yarn correctly set the resolution in the yarn.lock file as follows:
```
"lodash@npm:^4.17.11":
  version: 4.16.0
  resolution: "lodash@npm:4.16.0"
  checksum: 10/37d70b8a67edd4f3ef82ba3354de8dc4123ee9eddd84700a69edd3e2e3f8ae8d562162ed5af95d60810c333745c6ded9c8f432d19840387cde071ddcef5c6ec7
