Run the Naruto and Indian GST tests

[dpep]

Motivation / Background

This Pull Request has been created because two tests are named text_ instead of test_, so neither has ever run:

• test/faker/japanese_media/text_faker_naruto.rb is outside the test/**/**/test*.rb glob. It's been that way since cb72197 (2020). Renamed, its 4 tests pass.
• TestFakerCompany#text_indian_gst_number isn't picked up by Test::Unit. It's been that way since 205bc52.

Turning the GST test back on exposed two bugs it would have caught:

• Its regex allowed state codes 00–37, but indian_gst_number generates 02–38 and 98, as documented. The regex now matches what's documented.
• About 10% of generated numbers were 14 characters, not 15 (e.g. 13AGZHR303L5ZS). g_.int(length: 4, ranges: [0..9999]) ignores length when ranges is given (PositionalGenerator::Int), so values below 1000 weren't zero-padded. It now uses g_.int(length: 4) (1000–9999). That drops the 0001–0999 range real PANs allow, in exchange for always being 15 characters. Happy to pad instead if you'd rather keep the full range.

Additional information

5,000 generated GSTINs all match the updated regex and are all 15 characters.

This depends on #3326. With these tests running, the suite's fixed random sequence (the Random.new(42) that test_determinism leaves set) shifts and lands on a duplicate first name in test_nested_json_length. With #3326 merged in, rake test passes (2185 tests), and rubocop is clean.
