[BUG] License category "Unknown" for Unicode-DFS-2016 (Unicode Data Files and Software License 2016) — should be "Permissive"

[iersel]

Describe the bug
The license Unicode-DFS-2016 (Unicode Data Files and Software License 2016)
is categorized as "Unknown" instead of "Permissive". The SPDX identifier is
correctly detected, but the category classification is missing from the database.

To Reproduce
Steps to reproduce the behavior:

1. Open a project with make-plural@7.5.0 as a (transitive) dependency
   (e.g. via i18n-js@4.5.3 → make-plural@7.5.0)
2. Run Dependency Analytics
3. Open the license overview
4. See category "Unknown" for make-plural@7.5.0

Expected behavior
Unicode-DFS-2016 should be classified as "Permissive". It is a permissive
open-source license comparable to MIT/BSD — no copyleft, free for commercial use.
Valid SPDX identifier: https://spdx.org/licenses/Unicode-DFS-2016.html
