Add a problemMatcher

### How are you using the lua-language-server?

Visual Studio Code Extension (sumneko.lua)

### Which OS are you using?

MacOS

### What is the issue affecting?

Other

### Expected Behaviour

I am not sure how you normally run your Lua application. But I am used to use the tasks feature of VS code, so I created a tasks.json with this content:

```
{
// See https://go.microsoft.com/fwlink/?LinkId=733558
// for the documentation about the tasks.json format
"version": "2.0.0",
"tasks": [
{
"label": "Run main",
"type": "shell",
"command": "./main.lua",
"problemMatcher": [
"$lua"
]
"group": {
"kind": "build",
"isDefault": true
}
}
]
}
```

Normally such a task makes use of a `problemMatcher` which parses the tasks console output for problems and then highlight the code line that was affected. But there seems no problemMatcher to be defined by the plugin.

### Actual Behaviour

No problemMatcher provided.

### Reproduction steps

1. Create a tasks.json as given in "Expected Behaviour"
2. Crate a main.lua with an error such as "local i = 5 + "foo"
3. Run the task, the output shows something like
```
/usr/bin/lua: ./main.lua:3: attempt to add a 'number' with a 'string'
stack traceback:
[C]: in metamethod 'add'
./main.lua:3: in main chunk
[C]: in ?
```
See the main.lua, there is no highlight due to this error.

### Additional Notes

_No response_

### Log File

_No response_

未指定源文件或测试。使用提供的 tasks.json 和 main.lua 示例重现该问题，然后检查 VS Code 扩展如何参与任务集成和 problem matchers。完成的标准是：任务输出中的 Lua 运行时错误能够被解析，并且受影响的 main.lua 行被高亮显示。
