Redundant license "libzip" should just be BSD-3-Clause

[michellesenar]

Description

Per https://libzip.org/license/, the project is released under the BSD-3-Clause.

The above URL is what I'm redirected to when I click the homepage_url portion at https://scancode-licensedb.aboutcode.org/libzip.

I'm using an older scancode-toolkit version, but I see that this license still exists under the latest develop branch.
https://github.com/nexB/scancode-toolkit/blob/develop/src/licensedcode/data/licenses/libzip.LICENSE

How To Reproduce

scancode -l --json-pp output.json libzip.txt --license-text --license-text-diagnostics

output.json.txt

System configuration

Running this in Linux using scancode-toolkit 30.1.0 using source download the the /.configure script.

I am OK with deprecating license libzip
