Docs: Issue in Sampling example #7131
Description
What were you searching in the docs?
I was reviewing the documentation on sampling and testing out the example code. While running the example code I noticed that my sampling was not properly working. I eventually was able to get sampling to work by using sampling_rate instead of sample_rate when creating my logger. Additionally, in the source code sampling_rate is used and not sample_rate.
from aws_lambda_powertools import Logger
from aws_lambda_powertools.utilities.typing import LambdaContext
# Sample 10% of debug logs e.g. 0.1
logger = Logger(service="payment", sample_rate=0.1)
def lambda_handler(event: dict, context: LambdaContext):
logger.debug("Verifying whether order_id is present")
logger.info("Collecting payment")
logger.refresh_sample_rate_calculation()
return "hello world"
Is this related to an existing documentation section?

Hi @trevmt, thanks so much for opening this issue! You nailed it, our example is broken and using a wrong field name. Do you want to submit a PR to fix this? I'd love to have your contribution here. If you can't, no worries, I can fix it by end of this week.
