Describe the bug
A clear and concise description of what the bug is.

net.datafaker.idnumbers.NricNumber class CODE field has length 8 but is used to compute pair-wise weighted sum with random digits of length 7. The correct algorithm should have first value in array i.e. 0 removed.

To Reproduce
Code to reproduce

Expected behavior
A clear and concise description of what you expected to happen.

The value of new Faker(new Locale("en", "SG")).idNumber().singaporeanFin() should be valid with any online NRIC validator.

Versions:
Both Faker v1 and v2

Additional context
I have tested by patching the array and it works as expected.
