[BUG] npm pkg fix repository.url updates don't match documentation

[broksonic21]

Is there an existing issue for this?

• I have searched the existing issues

This issue exists in the latest npm version

• I am using the latest npm

Current Behavior

If you have a package.json with this:
See https://github.com/broksonic21/npm-pkg-fix/blob/main/package.json

  "repository": {
    "type": "git",
    "url": "https://github.com/broksonic21/npm-pkg-fix.git"
  },

then npm pkg fix converts it to:

 "repository": {
     "type": "git",
     "url": "git+https://github.com/broksonic21/npm-pkg-fix.git"
   },

(see https://github.com/broksonic21/npm-pkg-fix/pull/2/files )

Expected Behavior

That doesn't match the v10 docs at https://docs.npmjs.com/cli/v10/configuring-npm/package-json#repository which has the example canonical format to not include git+

{
  "repository": {
    "type": "git",
    "url": "https://github.com/npm/cli.git"
  }
}

I'd expect docs and npm pkg fix to match

Steps To Reproduce

1. with npm 10
2. with this package.json: https://github.com/broksonic21/npm-pkg-fix
3. Run npm pkg fix
4. See the package.json change

Environment

• npm: 10.2.0
• Node.js: v18.18.0
• OS Name: Mac Sonoma 14.0

It also converts broksonic21/npm-pkg-fix or github:broksonic21/npm-pkg-fix the same way, which is inconsistent with the CLI docs as well:

For GitHub, GitHub gist, Bitbucket, or GitLab repositories you can use the same shortcut syntax you use for npm install:

{
  "repository": "npm/npm",
  "repository": "github:user/repo",
  "repository": "gist:11081aaa281",
  "repository": "bitbucket:user/repo",
  "repository": "gitlab:user/repo"
}
