Sysix f61ae9ab42 fix(lsp): return default diagnostic report when server is not in pull mode (#27745)
Addresses one problem in #27736.
Clients should respect the the `ServerCapabilities` from the `intialize` response.
When no `diagnosticProvider` is provided, the server says to the client that `textDocument/diagnostic` is not supported.

```
        /**
	 * The server has support for pull model diagnostics.
	 *
	 * @since 3.17.0
	 */
	diagnosticProvider?: DiagnosticOptions | DiagnosticRegistrationOptions;
```
_https://microsoft.github.io/language-server-protocol/specifications/lsp/3.18/specification/#pull-diagnostics_

Sadly the client does not need to respect them and can requzest `textDocument/diagnostic` even if we told him not to do.
To avoid duplicate linting processes on push mode (server is sending diagnostics to the client on `didOpen/didChange`, we check if we are in the right mode, or else bail out earlier.
