🐛 Bug: Local path dependencies not recognized

[gramergrater]

Example input:

{
  "name": "test",
  "version": "1.0.0",
  "author": "test",
  "devDependencies": {
    "test": "file:./"
  }
}

Expected result:

{
  "valid": true
}

Actual result:

{
  "valid": false,
  "errors": [
    "Invalid version range for dependency test: file:./"
  ]
}

@gorillamania Shouldn't c15171c be cherrypicked?

Note that c15171c is against a pretty old fork of this repo, and would have merge conflicts trying to land now. The intent is good though - accepting PRs!

Per https://docs.npmjs.com/cli/v10/configuring-npm/package-json#local-paths, file: dependencies are allowed in npm.

Related: #71, for npm:, workspace:, and similar.
