Add support for dependencies preparation to general:cache-dep-licenses task

The `general:cache-dep-licenses` task is used to generate metadata about the licenses of the project's dependencies.

When using some dependency management systems, it is necessary to run an operation via the dependency management tool
prior to generating the metadata. A task call was added to the `general:cache-dep-licenses` task in order to allow it to
be used with such project types. It happens that such a preparatory operation is not necessary with the Go modules
dependency management system used by this project, so the preparation task is left empty.
