Description

Do you want to request a feature or report a bug?

feature

What is the current behavior?

If the current behavior is a bug, please provide the steps to reproduce.

if you have a lot of dependencies, it's a very long list of packages with the same license

What is the expected behavior?

a list of the licenses used, and some second way to see which package use license X (in the case that you for example can't use GPL or something, and quickly want to check for that)

Please mention your node.js, yarn and operating system version.

Research direction
Start by examining the existing implementation of the `yarn licenses list` command in the source code, likely in `src/cli/commands/licenses.js` or a related file. Review the current output format and logic. Consider how to aggregate licenses and then provide a command or flag to list packages by license. Check the issue comments for any additional guidance or requirements.
