### Which OS are you using?

Windows

### What is the issue affecting?

Libraries

### Expected Behaviour

`Lua.runtime.nonstandardSymbol` from addon's `config.json` should be correctly copied to `.vscode/settings.json`.

### Actual Behaviour

Only the LAST element of the addon's `Lua.runtime.nonstandardSymbol` array is being copied to `.vscode/settings.json` `Lua.runtime.nonstandardSymbol` array.

**Example**:

Input `addon/library/config.json`:

```
{
"name": "BWLua",
"words": ["--bwlua"],
"settings": {
"Lua.runtime.version": "Lua 5.1",
"Lua.runtime.special": {},
"Lua.runtime.builtin": {
"os": "disable",
"package": "disable",
"io": "disable",
"utf8": "disable",
"jit": "disable",
"debug": "disable",
"coroutine": "disable"
},
"Lua.runtime.nonstandardSymbol": ["`", "+=", "-=", "*=", "/=", "^=", "continue"]
}
}
```

Output `.vscode/settings.json`

```
{
"Lua.runtime.nonstandardSymbol": [
"continue"
],
"Lua.runtime.builtin": {
"io": "disable",
"utf8": "disable",
"debug": "disable",
"coroutine": "disable",
"package": "disable",
"os": "disable",
"jit": "disable"
},
"Lua.runtime.version": "Lua 5.1",
"Lua.workspace.library": [
".../LuaAddons/bwlua-language-addon/library"
]
}
````

Expected `"Lua.runtime.nonstandardSymbol"` value is: ```["`", "+=", "-=", "*=", "/=", "^=", "continue"]```

### Reproduction steps

1. Create an addon config at `addon/library/config.json` where `"Lua.runtime.nonstandardSymbol"` has an array with `>1` entries.
2. Enable addon in new workspace.
3. Observe `.vscode/settings.json`.

先重現 addon/library/config.json 的輸入，並將其與產生的 .vscode/settings.json 進行比較。追蹤 Lua.runtime.nonstandardSymbol 的 addon 設定傳遞，然後確認陣列中的所有項目都保留在工作區設定輸出中。
