make Brazilian ID Number accessible via faker.idNumber()

[asolntsev]

Brazilian ID Number (aka CPF) was already available via

faker.cpf().valid()

but now it's also available via more generic

new Faker(new Locale("pt", "BR")).idNumber().valid()

PR Summary

• Creation of BrazilIdNumber class
  A new module has been added that enables the generation of Brazilian taxpayer numbers (also known as CPF). This development will add to the range of identification number generators in the system.

• Improvement of IdNumberGeneratorPtBrUtil class
  This existing class has been made more secure by limiting access to certain methods. Extraneous and inefficient lines of code have also been taken out to make it more clean.

• Update in IdNumber.java class
  A correction was made in the documentation of an obsolete method which now accurately indicates that it generates valid Portuguese ID numbers.

• Services File Modification
  The newly created BrazilIdNumber class has been included in the official list of identification number generators. This allows its use across the application.

• Upgrade of IdNumberPatterns
  A new verification pattern has been added for Brazilian CPF numbers. This measure will help create valid identification numbers and enrich the ID number generation capabilities.

• New Tests Added for Brazilian ID numbers
  To ensure accuracy and reliability, a collection of tests have been added for Brazilian CPF numbers. These tests not only validate these numbers but also confirm that the system can generate both valid & invalid Brazilian CPFs.
