Redundant "Unable to execute code after break" diagnostic is given when using a label after a break

還沒有人認領這個 Issue。

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

Kakoune

### Which OS are you using?

Linux

### What is the issue affecting?

Diagnostics/Syntax Checking

### Expected Behaviour

No diagnostic is given.

### Actual Behaviour

A diagnostic `Unable to execute code after 'break'` is given, even though the only thing after the `break` is a label.

### Reproduction steps

Reproducible with the following code:
```lua
for i = 1, 10 do
if i < 8 then
print(i)
goto continue
end
break
::continue::
end
```

### Additional Notes

_No response_

### Log File

The log isn't very relevant in this case but here it is anyway.
[luals.log](https://github.com/LuaLS/lua-language-server/files/15503586/luals.log)

從 Diagnostics/Syntax Checking 下的 Lua 重現開始，並在 Linux 上透過 Kakoune 中的語言伺服器執行它。追蹤診斷 `Unable to execute code after 'break'` 的產生位置，然後確認當後續唯一的陳述式是 `::continue::` 標籤時，該診斷不存在。
