Description

When running a trivy scan on a node project, the following warning is shown when a latest version is used for a dependency:

Unable to parse "package.json" to remove dev dependencies: unable to walk dependencies: unable to match version for <package>

Example:

package.json

{
  "devDependencies": {
    "chromedriver": "latest",
    ...
  }
}

yarn.lock

chromedriver@latest:
  version "123.0.4"
  resolved "https://registry.yarnpkg.com/chromedriver/-/chromedriver-123.0.4.tgz#886886c79108b22b10f80925b67cecdc46d41988"
  integrity sha512-3Yi7y7q35kkSAOTbRisiww/SL2w+DqafDPAaUShpSuLMmPaOvHQR0i3bm2/33QBiQ8fUb1J/MzppzVL6IDqvhA==
  dependencies:
    "@testim/chrome-version" "^1.1.4"
    axios "^1.6.7"
    compare-versions "^6.1.0"
    extract-zip "^2.0.1"
    proxy-agent "^6.4.0"
    proxy-from-env "^1.1.0"
    tcp-port-used "^1.0.2"

Since latest is a valid version, should trivy be able to parse this?

Desired Behavior

Trivy scanner is able to parse latest version in package.json

Actual Behavior

Node scan can't parse package.json when latest is used as a package version, and therefore can't ignore dev dependencies.

Reproduction Steps

1. Include package with `latest` tag in package.json
2. Run `yarn` to create lock file
3. Run trivy node scanner on project, eg `trivy fs --scanners vuln --skip-dirs "node_modules" $1 --severity HIGH,CRITICAL --ignore-unfixed \
  --show-suppressed --exit-code 1`
