Describe the bug
After upgrading to python 3.12 pylint started complaining about invalid escape sequence '\w' which I traced to pyaml_env and more precisely to line 58 in parse_config:

 type_tag_pattern = re.compile(f'({type_tag}\w+\s)')

To Reproduce Steps to reproduce the behavior:

1. Create a test_read.py file with the following content:

"""Test for pyaml_env parse_config call"""
from pyaml_env import parse_config

def read_config():
    """Reads config from the app.yaml file"""
    return parse_config('app.yaml')

2. Run pylint on this file

(.venv) bernt@work:~/python/projectx$ pylint test_read.py

3. Results:

<unknown>:58: SyntaxWarning: invalid escape sequence '\w'

Expected behavior pylint shouldn't complain about a valid pattern.

The complaints can be removed by specifying a raw pattern to compile:

 type_tag_pattern = re.compile(fr'({type_tag}\w+\s)')

Additional context
