[Bug] buildSync api do not respect tsconfig.json when use stdin input.

[Akimyou]

I config "jsxFactory": "h" and "jsxFragmentFactory": "Fragment" in tsconfig.json.

When use entryPoints: ['./test-tsx.tsx'], the result is correct.

const { warnings, outputFiles } = buildSync({
  tsconfig: './tsconfig.json',
  entryPoints: ['./test-tsx.tsx'],
//   stdin: {
//       contents: testTsxContent,
//       loader: 'tsx',
//   },
  write: false,
})

Result:

const render = () => {
  return /* @__PURE__ */ h(Fragment, null, /* @__PURE__ */ h("h1", null, "Hello"));
};

When use stdin, the result is different, seems like not respect tsconfig.json.

const render = () => {
  return /* @__PURE__ */ React.createElement(React.Fragment, null, /* @__PURE__ */ React.createElement("h1", null, "Hello"));
};
