chore: add chef/chef-licensing gem license location

[ahasunos]

Description

A validate build for the Infra client, after adding the chef-licensing dependency, failed with the following error:

Encountered error(s) with project's licensing information.
--
  | Failing the build because :fatal_licensing_warnings is set in the configuration.
  | Error(s):
  |  
  | Dependency 'chef-licensing' version '1.0.2' under 'ruby_bundler' is missing license files information.
  | >> Found 145 dependencies for ruby_bundler. 144 OK, 1 with problems
  | If you are encountering missing license or missing license file errors for **transitive** dependencies, you can provide overrides for the missing information at https://github.com/chef/license_scout/blob/1-stable/lib/license_scout/overrides.rb#L93.
  | Promote license_scout to Rubygems with `/expeditor promote chef/license_scout:1-stable X.Y.Z` in slack.

This PR adds the license information for the chef-licensing gem.

This update ensures that license_scout can successfully locate and report the license information for the chef-licensing gem.
