Confusing undocumented behavior of "root" Configuration property name.

[jnhnum1]

Using dependency-injector version 4.45.0 in Python 3.13.1 in MacOS 14.5.

Minimal reproducible example:

from dependency_injector.providers import Configuration

config = Configuration()
config.from_dict(
    {"a": {"root": 3}}
)

assert config.a.root() == 3, f"Expected 3, got {config.a.root()}"

Skimming the source, it appears the issue is here: https://github.com/ets-labs/python-dependency-injector/blob/6e4794bab18fef3ffbc6a11bee526fe24688286f/src/dependency_injector/providers.pyx#L1595C1-L1597C26

It doesn't appear that this "root" property is used anywhere, nor is it documented at https://python-dependency-injector.ets-labs.org/providers/configuration.html
