[BUG] Ark Survival Evolved: Unable to display game details

## User Story

As a user, I want 'arkserver details' to output server name, password and admin password.

## Basic info

- **Distro:** Debian 11
- **Game:** Ark Survival Evolved
- **Command:** details
- **LinuxGSM version:** [v22.2.1]

## Further Information

The details command always display "NOT SET" as follows:
```
Server name: NOT SET
App ID: 376030
...
Server password: NOT SET
Admin password: NOT SET
```

## To Reproduce

Steps to reproduce the behaviour:

1. Install Ark as described on website
2. Execute details command

## Expected behaviour

I expect to see server name and admin password to be displayed.

Ark seems to store `GameUserSettings.ini` with UTF-16LE encoding. Even if this file is converted with iconv, ark seems to rewrite it on next start. As `sed` is unable to parse this file we are faced with `NOT SET` strings.

With additional convertion sed works again.
See this for reference:

```
iconv -f utf-16le -t utf-8 ${servercfgfullpath} -o ${servercfgfullpath}.utf8
servername=$(sed -nr 's/^SessionName=(.*)/\1/p' "${servercfgfullpath}.utf8")
adminpassword=$(sed -nr 's/^ServerAdminPassword=(.*)/\1/p' "${servercfgfullpath}.utf8")
serverpassword=$(sed -nr 's/^ServerPassword=(.*)/\1/p' "${servercfgfullpath}.utf8")
```
