setting `port` in terminating gateway causes Envoy configuration to fail

### Nomad version
v1.6.2

### Issue
Creating a Consul Terminating Gateway using the [gateway block](https://developer.hashicorp.com/nomad/docs/job-specification/gateway) fails to bind an envoy listener when in bridged network mode. Substituting `mode = "bridge"` with `mode = "host"` allows the end-to-end test to be successful.

### Reproduction steps
1. Register the external service

Catalog Registration Random Message

```sh
curl -X PUT -H "X-Consul-Token: $CONSUL_HTTP_TOKEN" \
http://localhost:8500/v1/catalog/register -d '{
"Node": "external",
"Address": "whatthecommit.com",
"NodeMeta": {
"external-node": "true",
"external-probe": "true"
},
"Service": {
"Service": "random-message",
"Address": "whatthecommit.com",
"Port": 443
}
}'
```

3. Deploy the TGW

Job Spec

```sh
job "terminating-gateway" {
datacenters = ["*"]

group "terminating-gateway" {

network {
mode = "bridge"
port "envoy" {}
}

service {
name = "terminating-gateway"
port = "envoy"
connect {
gateway {
proxy {}
terminating {
service {
name = "random-message"
sni = "whatthecommit.com" # /index.txt
ca_file = "/etc/ssl/certs/ca-certificates.crt"
}
}
}
}
}
}


group "alpine" {
network {
mode = "bridge"
}

service {
name = "alpine"
connect {
sidecar_service {
proxy {
upstreams {
destination_name = "random-message"
local_bind_port = 8888
}
}
}
}
}

task "alpine" {
driver = "docker"
config {
image = "alpine:3.18.4"
command = "${NOMAD_TASK_DIR}/loop.sh"
}

template {
destination = "${NOMAD_TASK_DIR}/loop.sh"
perms = "755"
data = <<-EOF
#!/bin/sh
apk add curl jq iproute2-ss

while true ; do
sleep 86400
done
EOF
}
}
}
}
```

4. Create the service intention

Allow Alpine -> Random Message

```sh
curl -X PUT -H "X-Consul-Token: $CONSUL_HTTP_TOKEN" \
http://localhost:8500/v1/config -d '{
"Kind": "service-intentions",
"Name": "random-message",
"Sources": [{
"Name": "alpine",
"Action": "allow"
}]
}'
```

6. Validation
`nomad alloc exec -task=alpine curl localhost:8888/index.txt`

#### Expected Result
`nomad alloc exec -task=alpine curl localhost:8888/index.txt` should produce a random commit message.

#### Actual Result
No listener has been created, but the allocations are in a running state. Consul agent logs lead me to infer that Nomad is attempting to pass-in a faulty configuration for Envoy's bootstrap configuration.

##### Consul Agent logs

```log

##### Snippet from the catalog endpoint
Particularly the "Config" section

```json
"ServiceMeta": {
"external-source": "nomad"
},
"ServicePort": 21990,
"ServiceSocketPath": "",
"ServiceEnableTagOverride": false,
"ServiceProxy": {
"AccessLogs": {
"Enabled": true,
"Type": "stdout"
},
"Mode": "",
"Config": {
"connect_timeout_ms": 5000,
"envoy_gateway_bind_addresses": {
"default": {
"Address": "0.0.0.0",
"Port": -1
}
},
"envoy_gateway_no_default_bind": true,
"protocol": "http"
},
"MeshGateway": {
"Mode": "local"
},
"Expose": {}
```

No source file or test is named. Start by reproducing the terminating gateway job in bridged network mode and trace the gateway block through Nomad's generated Consul/Envoy configuration, focusing on envoy_gateway_bind_addresses. Done means the Envoy listener is created and the Alpine request to localhost:8888/index.txt returns a random commit message.
