Describe the Bug

Pruned yarn.lock results in merging npm: prefixed versions & non-prefixed versions

"string-width-cjs@npm:string-width@^4.2.0", string-width@4.2.3, string-width@^4.1.0, string-width@^4.2.0, string-width@^4.2.3:
  version "4.2.3"
  resolved "https://registry.yarnpkg.com/string-width/-/string-width-4.2.3.tgz#269c7117d27b05ad2e536830a8ec895ef9c6d010"
  integrity sha512-wKyQRQpjJ0sIp62ErSZdGsjMJWsap5oRNihHhu6G7JVO/9jIB6UyevL+tXuOqrng8j/cxKTWyWUwvSTriiZz/g==
  dependencies:
    emoji-regex "^8.0.0"
    is-fullwidth-code-point "^3.0.0"
    strip-ansi "^6.0.1"

Expected Behavior

Split yarn.lock entries starting with the npm: prefix

"string-width-cjs@npm:string-width@^4.2.0":
  version "4.2.3"
  resolved "https://registry.yarnpkg.com/string-width/-/string-width-4.2.3.tgz#269c7117d27b05ad2e536830a8ec895ef9c6d010"

  dependencies:
    emoji-regex "^8.0.0"
    is-fullwidth-code-point "^3.0.0"
    strip-ansi "^6.0.1"

string-width@^4.1.0, string-width@^4.2.0, string-width@^4.2.3:
  version "4.2.3"
  resolved "https://registry.yarnpkg.com/string-width/-/string-width-4.2.3.tgz#269c7117d27b05ad2e536830a8ec895ef9c6d010"
  integrity sha512-wKyQRQpjJ0sIp62ErSZdGsjMJWsap5oRNihHhu6G7JVO/9jIB6UyevL+tXuOqrng8j/cxKTWyWUwvSTriiZz/g==
  dependencies:
    emoji-regex "^8.0.0"
    is-fullwidth-code-point "^3.0.0"
    strip-ansi "^6.0.1"

To Reproduce

1. Have the split yarn.lock entries in your original yarn.lock
2. Prune repo
3. Check pruned yarn.lock
4. See that they are merged again

Important parts in the repro;

package.json (versions defined) https://github.com/Netail/repro-yarn-lock/blob/main/apps/web/package.json#L5-L8

yarn.lock (how the yarn.lock entries also should look like after being pruned) https://github.com/Netail/repro-yarn-lock/blob/main/yarn.lock#L25-L41

Currently blocking us from optimally using prune in our CI as we have to delete the pruned yarn.lock and generate a new yarn.lock based on the pruned repo. Slowing the pipeline a bit :(
