fix(locales): remove wrong phone number in Portugal

[MarioRodrigues10]

This PR removes the incorrect phone number "+351 3########" from the Faker library's Portugal phone number generator.

The last major revision to the numbering plan for Portuguese phone numbers was made in 1999, with the introduction of a new numbering plan by the Portuguese National Communications Authority (ANACOM). This plan introduced new area codes and changed the format of Portuguese phone numbers to the current nine-digit format, with numbers starting with "2" used for landlines and numbers starting with "9"used for mobile phones.
