Fixes #4942

Short GNU GPL v2 release notices match unrelated partial composite rules instead of an exact GPL v2 notice.

Add two exact GPL v2 notice rules and cover both license/licence spellings with full-coverage hash-match regressions.

Validation on Python 3.12, with a fresh license index:

• python -m pytest -q tests/licensedcode/test_match_hash.py tests/licensedcode/test_license_models.py — 53 passed.
• The new regression fails on unchanged develop.

CI baseline comparison

The Python 3.14 license_validate_ignorables_2 job fails two assertions for missing ignorable URLs in fsl-1.1_1.RULE and fsl-1.1_2.RULE. Both assertions fail with the same output on upstream commit e423b48a1fdbff26219fbeafe7e9bdef293b91fc. The PR has 31 passing checks. Azure reports the failed job and its parent pipeline separately.
