AWS Secrets Manager's environment name mismatch

[mat-alfa]

I'm using concourse-ci version 5.0.0

I found the environment variable of AWS_REGION, which describe inhttps://concourse-ci.org/aws-asm-credential-manager.html, didn't work.

Some clue here: https://github.com/concourse/concourse/commit/5d30023589f168ee3fd3309e19c90ede516176d0 After try-n-error, I found that changing env setting from "AWS_REGION" to "CONCOURSE_AWS_SECRETSMANAGER_REGION" solve my problem. I guess AWS SSM credential manager have the same problem, and this might apply to them, too. So, I report the issue here and hope the document can be updated if the fix was verified.

Regards.
