Incorrect examples in project template for `credentials.yml`

[ElenaKhaustova]

Description

Dataset access credentials example includes the correct way to pass credentials for AWS, while the project template includes an outdated example.

Context

The discrepancy between those two sources confuses users and when following the example from the template they face issues, aka

TypeError: AioSession.__init__() got an unexpected keyword argument 'aws_access_key_id'

Expected Result

The project template includes correct examples for setting the credentials.
