Faker returns one value when using multiple locales

See original GitHub issue

Faker version: 13.11
OS: Mac OS Monterey Computer: MacBook Pro (14-inch, 2021)

Brief summary of the issue goes here. If using multiple locales, faker only makes one choice. This only happens when you select multiple locales

Steps to reproduce

from faker import Faker

fake = Faker(["en_GB", "fr_FR", "en_IN"])
Faker.seed(0)
for _ in range(5):
    print(fake.date_time_this_year())

@princelySid Yes good call. I just pushed a change. I think this test asserts two things:

1/ that the values are not all the same

2/ that the lists are the same between instances of Faker - which should confirm that nothing needs to be re-seeded on each call to a faker method

I made these changes: https://github.com/johntmyers/faker/commit/a264c268f81e803fa5ba6da3ca868be1da738b2c - which seems to work fine. I updated the test as well which basically makes sure that when seeding is used with multiple locales, you get consistent output for each method. I’m happy to open this as a PR but would still like to understand if there was some other intent that was missing.
