The canonical linux-firmware Airoha license was detected as MediaTek. Add an airoha-firmware license definition so it is identified as Airoha, with a regression fixture copied from the canonical upstream text and pinned source provenance. Update the changelog and contributor credits.

Refs #5394. This addresses the Airoha detection case without closing the broader issue.

Validation

• On develop at e423b48a1fdbff26219fbeafe7e9bdef293b91fc: 1,798 selected detection corpus tests, 2 metadata tests, and 8 peer validation checks passed. Two FSL failures reproduce unchanged on the base.
• Against the exact head of PR Add AIC and AEONSEMI firmware license detection #5404: 12 API cases, 3 firmware fixtures, 2 metadata tests, and 12 canonical checks passed.
• The full suite has not been established as passing. Azure CI completed with 29 jobs passed and one failed on two FSL ignorable URL assertions also present in exact-base build 19673; the new Airoha test passed. DCO and Read the Docs passed. Three GitHub workflows (CI About Files, CI Documentation, and GitHub Actions Security Analysis with zizmor) await maintainer approval and have not run.
