AttributeError: 'MyConfigParser' object has no attribute 'readfp'. Did you mean: 'read'?

Reproduction steps:

1. Install jinja2-cli in a virtualenv

gh repo clone mattrobenolt/jinja2-cli jinja2cli && cd jinja2cli
python -m virtualen .venv
source .venv/bin/activate
pip install -e .

2. create a ini data file and a template:

• data.ini file:

[data]
foo=bar
ham=spam

• template.j2 file:

## Data:

- foo: {{ data.foo }}
- bar: {{ data.bar }}

3. run the commands:

jinja2 ./data.ini ./template.j2

According to Python 3.12 documentation, ConfigParser.read_file replaced ConfiggParser.readfp(), and ConfigParser.readfp() is no longer recognized.
