Benin moved from 8-digit to 10-digit phone numbers on 30 November 2024: every number got the 01 prefix, and 8-digit numbers stopped working when the parallel-running period ended on 29 December 2024.

The fr-BJ rule (/^(\+229)\d{8}$/) still expects 8 digits. As a result, isMobilePhone rejects every current Beninese mobile number, such as +2290197123456, and accepts 8-digit numbers that no longer exist.

This PR:

• matches 01 followed by the mobile ranges, using the same pattern as Google libphonenumber's BJ mobile metadata: 01(2[5-9]|[4-69]\d)\d{6};
• excludes the fixed-line ranges 0120–0124;
• keeps +229 mandatory, as before;
• replaces the valid test numbers with mobile numbers. The old ones, +22920… to +22923…, were fixed-line numbers;
• adds invalid cases: old 8-digit numbers, new fixed-line numbers, unallocated ranges, wrong lengths, and a missing +.

The ITU table lists 0125–0129 as "fixed and mobile" series. Google classifies them as fixed-line-or-mobile and includes them in its mobile pattern, so this PR accepts them too.
