check_model_has_meta_keys check doesn't work with meta keys with a list of values

[LoekBotman]

Hi! I'm considering using the dbt-bouncer package in our dbt project to enforce our dbt conventions and I really like it so far. I just ran into one issue that seems to be a bug in the check_model_has_meta_keys check.

If I add the following meta data to my dbt model:

meta:
  key_1: abc
  key_2:
    - a
    - b
    - c

And I define my dbt-bouncer check like this:

- name: check_model_has_meta_keys
  include: ^models/entities
  keys:
    - key_1
    - key_2

I get an error saying that my model is missing the key key_2.

I expect that it's related to row 82 in the src/dbt_bouncer/utils.py file in (the function find_missing_meta_keys).

I wonder if it's indeed a bug or if there's a reason why it should fail. And if it's a bug, is it something you can fix in a later version?

@LoekBotman Looks like a bug to me. Added a fix in #345 and released in 1.10.1. Let me know if it works for you!

This works perfectly. Thanks for the quick response!
