Update license_scanning_spec.rb - Remove BSD Zero license

What does this MR do and why?

As per https://gitlab.com/gitlab-org/gitlab/-/issues/469478 and the discussion at &13489 (comment 1973276271) , we can't find a package in the test that uses 0BSD license. I have verified this with third party tools.

The original license was misapplied for 2 packages - see https://gitlab.com/gitlab-org/gitlab/-/issues/469478#note_1973485996

As per &13489 (closed) - we've moved license checking to deps.dev, so it appears we've improved the accuracy of results. This MR removes the erroneous license.
