This precommit check falsely detects AWS keys in the folders with C# build artifacts at src/cloud/providers/azure/sidecar.

This check is extremely basic. All it does is search all files, no matter if they are gitignored or not, for the AWS key regexp: https://github.com/blaircalderwood/scan-for-secrets/blob/master/src/constants.js

It is also not configurable, and one can't exclude certain folders from scanning.

In this MR, I point the check to the AWS folder instead of scanning through all the source files.

Down the road I suggest to replace this check with https://www.npmjs.com/package/detect-secrets or to improve the existing tool, e.g. via contributing a folder exclusion feature.
