### User story

Pallworld server script config is missing perams in the lgsm server config

### Game

Palworld

### Linux distro

Ubuntu 22.04

### Command

command: start

### Further information

Pallworld server script config is missing
`Port='${port}'`
and
`-publicport='${port}'`
in startperams. It should look like this,
`startparameters="EpicApp=PalServer Port='${port}'-useperfthreads -NoAsyncLoadingThread -UseMultithreadForDS -servername='${servername}' -publicport='${port}'"`
Otherwise you wont be able to connect to the server using custom ports.

### Relevant log output

```shell
NA
```

### Steps to reproduce

Install default lgsm server script for palworld, assign custom ports.
