fix: remove end of string space

[JeferCatarina]

what

As there is a whitespace before closing the quotes, when trying to enable notifications, Terraform always try to set it to null:

Code snippet:

  environments = {
    main = {
      branch_name               = "main"
      enable_notification      = true
[...]

Output:

  # module.amplify_app.aws_amplify_branch.default["main"] will be updated in-place
  ~ resource "aws_amplify_branch" "default" {
      - enable_notification           = true -> null
        id                            = "xxxxxxxxxxxxxx/main"
        tags                          = {}
        # (21 unchanged attributes hidden)
    }
