ignoring changes to maintenance_track_name variable

[mia-paystack]

what

Ignore changes to the Terraform variable maintenance_track_name for the Redshift cluster resource.

why

Terraform is attempting to update maintenance_track_name due to a value managed outside our Terraform configuration. Since AWS does not allow us to explicitly set this value in our configuration, the change is being ignored to prevent unnecessary updates.

Example plan output:

# aws_redshift_cluster.default will be updated in-place
  ~ resource "aws_redshift_cluster" "default" {
        id                                   = "paystack-staging-data-platform"
      ~ maintenance_track_name               = "dc2ltm" -> "current"
    }
