refactor(language_server): send in memory source text to tsgolint (#14733)

counterpart of oxc-project/tsgolint#291

the downstream  PR successfully lints the in memory file:
![tsgolint-in-memory](https://github.com/user-attachments/assets/5409c5e5-bda5-44f9-bea7-6ce0a64f2502)

It is just a refactoring because the `TsgoLinter` will still only be used `onSave`
