jfrog aud --yarn fails on Yarn v4 despite v2.104.1 adding Yarn v4 support

[kellsbells]

Describe the bug

jfrog aud --yarn fails on Yarn v4 monorepos despite v2.104.1 release notes explicitly listing Yarn v4 support (RTECO-1035).

Current behavior

Every package in the monorepo fails with:
failed to build dependency tree: failed while building 'yarn' dependency tree: failed to configure an Artifactory resolution server or running and install command: resolving Yarn dependencies from Artifactory is currently not supported for Yarn V1 and Yarn V4. The current Yarn version is: 4.5.3

Reproduction steps

1. Have a Yarn v4 (Berry) monorepo with yarnPath: .yarn/releases/yarn-4.5.3.cjs set in .yarnrc.yml
2. Install jfrog CLI v2.104.1
3. Run jfrog aud --yarn
4. Observe error above for every package in the workspace

Expected behavior

Audit runs successfully and generates a dependency tree using Yarn v4 as advertised in the v2.104.1 release notes: https://github.com/jfrog/jfrog-cli/releases/tag/v2.104.1
