Fix where we place the sql cli include directory

[tatiana]

Describe the bug
When installing the SQL CLI python library, it's incorrectly adding the include directory in the root of the site-packages.

Version

• SQL CLI: 0.2.2

To Reproduce

$ python3 -mvenv venv
$ source venv/bin/activate
$ pip install astro-sql-cli
$ tree venv/lib/python3.8/site-packages/include/
venv/lib/python3.8/site-packages/include/
└── base
    ├── config
    │   ├── default
    │   │   └── configuration.yml
    │   ├── dev
    │   │   └── configuration.yml
    │   └── global
    │       └── configuration.yml
    ├── data
    │   ├── imdb.db
    │   └── retail.db
    └── workflows
        ├── example_basic_transform
        │   └── top_animations.sql
        ├── example_load_file
        │   ├── load_imdb_movies.yaml
        │   └── transform_imdb_movies.sql
        └── example_templating
            ├── filtered_orders.sql
            └── joint_orders_customers.sql

Expected behaviour

The include directory It should be inside the sql_cli package:

venv/lib/python3.8/site-packages/sql_cli/
