feat: Support for projects with multiple/nested workspaces

[MLSTRM]

Currently this plugin will only resolve the dependencies/components for a single workspace at a time, which can introduce additional complexity/complication when working in a multi-workspace monorepo.
Enhancing the plugin to recursively traverse all nested workspaces is quite a small change and would simplify the usage of this plugin in more complex projects, especially in cases where isolated reporting of BOM information is not required.

I've made an initial proof of concept branch for what the change for this could look like on my own fork here for now https://github.com/MLSTRM/cyclonedx-node-yarn/tree/feature/nested-workspace-traversal - need to rebase past some changes in the last couple of days before I can raise a proper PR if deemed a useful thing to have

PRs are welcome. Please make sure to follow the contribution guidelines, and add relevant test cases and test-beds

PR raised + test added, also noticed the old snapshots weren't updated since the license resolution removal so I've updated those at the same time.
