Add package path to json list

[krzysztof-pawlik-gat]

Summary

licensed tool for auditing licenses of packages needs to have a directory where a package is installed. Right now even for applications using yarn it will fallback to using npm to list dependencies, to fix that yarn needs to output a directory where files for each package are available.

Test plan

Tests have been updated, the only tricky part was that each test run will generate a different path (due to using /tmp and one-time directories in it), hence special care had to be taken to account for this.

Tests will be failing due to expired certificates until #7457 is merged.

@krzysztof-pawlik-gat #7457 has been merged, could you update CHANGELOG.md again?

[krzysztof-pawlik-gat]

@rockwyc992 thanks! I've updated CHANGELOG.md and updated tests so they don't fail on Windows. All checks passing.

Lint seems to be failing on master since #7512 got merged.

Waiting for this as well to be able to use licensed for yarn.
