Could the Yarn Install Buildpack support native Yarn caching?

[kvedurmu]

It looks like yarn supports a cache-dir flag. Could we use this between builds to reduce the change that on a rebuild we actually have to reach out to a yarn repository and download packages
see:

• https://classic.yarnpkg.com/en/docs/cli/cache/
• yarnpkg/yarn#5778

@paketo-buildpacks/nodejs-maintainers Is this still a relevant feature request?
