Remove code for unsupported license_management

Support for the `license_management` artifact/scanner was dropped in
13.0 (see https://gitlab.com/groups/gitlab-org/-/epics/659), but this
code was left over, and is now effectively a no-op. This simply removes
that code.

Addresses part of https://gitlab.com/gitlab-org/gitlab/-/issues/8912.
