Support 'textDocument/diagnostic' method and 'diagnosticProvider' capability

How are you using the lua-language-server?

Command Line

Which OS are you using?

Linux

What is the issue affecting?

Diagnostics/Syntax Checking

Expected Behaviour

Server's capabilities contain the 'diagnosticProvider' and lua language server supports method "textDocument/diagnostic"

Actual Behaviour

Server's capabilities don't contain the 'diagnosticProvider' and doesn't support method "textDocument/diagnostic"

Reproduction steps

1. Get initialize response from server with capabilities
2. Check capabilities list
3. Send "textDocument/diagnostic" request

Additional Notes

從 script/proto/proto.lua 開始，這裡的日誌會回報未知的 textDocument/diagnostic 方法；接著查看 script/provider/provider.lua，這裡會組合伺服器能力。追蹤現有的診斷流程與 LSP 請求處理。完成的標準是 initialize 回應宣告 diagnosticProvider，並且支援 textDocument/diagnostic 請求，同時不再出現未知協定警告。
