More partition hardcoding

Describe the Bug

$ grep ':aws:' lambda*.tf
lambda-log.tf:  source_arn    = "arn:aws:s3:::${each.value}"
lambda-log.tf:    resources = concat(formatlist("arn:aws:s3:::%s", var.s3_buckets), formatlist("arn:aws:s3:::%s/*", var.s3_buckets))
lambda-log.tf:  source_arn    = "arn:aws:logs:${local.aws_region}:${local.aws_account_id}:log-group:${each.value}:*"
lambda-rds.tf:  source_arn    = "arn:aws:logs:${local.aws_region}:${local.aws_account_id}:log-group:RDSOSMetrics:*"
lambda-vpc-logs.tf:  source_arn    = "arn:aws:logs:${local.aws_region}:${local.aws_account_id}:log-group:${var.vpclogs_cloudwatch_log_group}:*"

This among other possible issues, doesn't associate the correct arn with the lambda triggers resulting in
