🐞fix(emotion): support ESM for createX #338

[xcfox]

Summary

support ESM for createX in @xtyled/emotio, and fix #338 It may be a mistake in https://github.com/gregberge/xstyled/commit/292fe28d71c280cb755ed4ecf01ac6deae693031.

Test plan

Previous output code in dist/index.esm.js use emStyled directly:

...
const createX = (generator) => {
  const styled = createBaseStyled(createCssFunction(generator), generator);
  const x = {};
  Object.keys(emStyled).forEach((tag) => {
    x[tag] = styled(tag)``;
  });
  return x;
};
...

After fix:

...
const createX = (generator) => {
  const styled = createBaseStyled(createCssFunction(generator), generator);
  const x = {};
  Object.keys(emStyledInterop).forEach((tag) => {
    x[tag] = styled(tag)``;
  });
  return x;
};

...
