Describe the problem

Since I upgraded to dlt v0.4.8 I get this nasty warning. With v0.4.7 it is not present:

Expected behavior

The rest api source should not throw a warning when no authentication is provided because some APIs do not require authentication.

Steps to reproduce

import dlt

from rest_api import rest_api_source

pokemon_config = {
    "client": {
        "base_url": "https://pokeapi.co/api/v2/",
    },

    "resources": [
        "berry",
    ],
}

pokemon_source = rest_api_source(pokemon_config)

pipeline = dlt.pipeline(
    pipeline_name="pokemon_pipeline",
    destination="duckdb",
    dataset_name="pokemon",
    progress="log",
)

load_info = pipeline.run(pokemon_source)
print(load_info)
