Analyses cause check-model-has-description failure

[tim-steinkuhler]

Describe the bug
When I added an analysis file accompanied by a yaml file with a description, check-model-has-description still fails, saying it doesn't have a description.

This can be fixed by either excluding analyses from this check or correctly looking for analysis descriptions.

To Reproduce
Steps to reproduce the behavior:

1. Install codegen with dbt deps
2. Create a sql file in the analyses folder, and a yaml file with a description
3. run the check-model-has-description check

# packages.yml
packages:
  - package: dbt-labs/codegen
    version: 0.8.1

--generate_model_yaml.sql
{{ codegen.generate_model_yaml(
    model_name='base_trengo_tickets_tickets_custom_data'
) }}

# generate_model_yaml.yml
version: 2
analyses:
  - name: generate_model_yaml
    description: >
        This analyses generates the input necessary for a .yml file,
        by adding the model name without extensions and then hit compile.
        The output can then be copied and pasted into the designated yml file.

Expected behavior
I expect check to pass
