fix(syncer): enable SSE by default for dist bucket

[npalm]

Description

Amazon has enabled SSE by default for S3 buckets since Jan 2023. Currently the module does set the default rule to null, which results that every run detects a change in SSE for the dist bucket. By setting the default to SSE the Terraform default config is back in sync with the AWS default.

Problem

Every Terraform run tries to change the bucket encryption settings due to Amazon default changes:

Terraform will perform the following actions:

  # module.runners.module.runner_binaries[0].aws_s3_bucket_server_side_encryption_configuration.action_dist[0] will be updated in-place
  ~ resource "aws_s3_bucket_server_side_encryption_configuration" "action_dist" {
        id     = "np-default-dist"
        # (1 unchanged attribute hidden)

      - rule {
          - bucket_key_enabled = false -> null

          - apply_server_side_encryption_by_default {
              - sse_algorithm = "AES256" -> null
            }
        }
      + rule {
        }
    }

Plan: 0 to add, 1 to change, 0 to destroy.
