Please move the @deprecated tag down to comply with #512

[Shinigami92]

Could you please add a check in the test that the warning is called?
We already do this for methods in random here:

faker/test/random.spec.ts

Line 239 in 2d68da1

`Deprecation Warning: faker.random.${functionName} is now located in faker.${newLocation}`
