fix(isMobilePhone): fix mk-MK regex to correctly validate Macedonian mobile numbers

The previous regex used `7[0-9][2-9]\d{5}` which incorrectly restricted
the third digit to 2-9, causing valid mobile numbers like +38970123456
and 070123456 (070-079 range) to fail validation. Fixed to `7[0-9]\d{6}`
to allow all valid Macedonian mobile operator prefixes.

Fixes #2497
