Pattern ^[34][34]\d{2}$ is too restrictive for Ukrainian year formatting

The test cases across multiple languages show that years between 3000-4000 follow consistent formatting patterns. The current regex ^[34][34]\d{2}$ only matches years like 3300-3499 and 4300-4499, but excludes valid cases like 3500-3999 that should follow the same format rule.

The pattern should be changed to ^[34]\\d{3}$ to cover all years in the 3000-4999 range
Line 14 can be removed since its pattern is now redundant with line 15
