Commands are not aggregating when running multiple templates

### Configuration

```hcl
# {{ ansible_managed }}

vault {
address = "http://127.0.0.1:8100"
renew_token = false
retry {
# Settings to 0 for unlimited retries.
attempts = 0
}
}

consul {
address = "127.0.0.1:8500"
retry {
# Settings to 0 for unlimited retries.
attempts = 0
}
}

wait {
min = "15s"
max = "30s"
}

# Postgres CA
template {
source = "/etc/consul-template/templates/keystone/postgres-server-ca.crt.ctmpl"
destination = "/etc/keystone/postgres-server-ca.crt"
create_dest_dirs = false
perms = "0644"
exec {

}
}

# Postgres User

`/etc/consul-template/templates/keystone/postgres-user-keystone.ctmpl`

```

### Expected behavior

The command `sudo systemctl reload-or-restart apache2 || true` to only run once on initial rendering.

### Actual behavior

What actually happened?

The command `sudo systemctl reload-or-restart apache2 || true` ran multiple times.

You can see it ran on `2025-03-16T13:46:14.478-0500` and `2025-03-16T13:46:14.555-0500`

### Steps to reproduce

1. Use my config and templates above.

Reproduce the behavior with the supplied Consul Template configuration and debug output, focusing on how exec commands from multiple templates are collected and run. Confirm the expected aggregation behavior when both templates render, then verify that the resulting command handling matches that behavior without breaking single-template execution.
