Fixes warnings in desktop-file-validate (#5822) ...

Trying to validate this desktop entry with `desktop-file-validate` (default tool for desktop entry validation) shows the following warnings.
```bash
~$ desktop-file-validate unciv.desktop
unciv.desktop: warning: key "Encoding" in group "Desktop Entry" is deprecated
unciv.desktop: warning: boolean key "Terminal" in group "Desktop Entry" has value "0", which is deprecated: boolean values should be "false" or "true"
```
Thus deprecated lines were removed or edited.
