A few issues which prevent to upgrade Amazon Ads connector to latest cdk version

[Vadym5]

Description

I'm trying to upgrade Amazon Ads to latest version (6.44.0) and have a few issues in case of it.

Issues

1. Issue with "max_concurrent_async_job_count". I set "max_concurrent_async_job_count" in the manifest.yaml as "3". But in any case i have "1" as value which is really used. - issue [Amazon ads] Connector can't upgrade to latest python-cdk version > "max_concurrent_async_job_count" ignored airbyte#57009
2. Download report decode issue with gzip. Amazon Ads don't send proper header to us, so we need to set a default for it [source-amazon-ads] Connector can't upgrade to latest python-cdk version > GZIP error airbyte#56988
3. Interpolation context missed - Source Amazon Ads: Update the manifest to use the latest AsyncRetriever changes airbyte#55806 (comment)
