Description

Closes #1127 by using the classic React.createElement function rather than the newer jsx-runtime transform.

Per babel docs: https://babeljs.io/docs/en/babel-preset-react#with-a-configuration-file-recommended

Issue

Fixes: #1127

Example
Now builds look like this:

const ToolbarAlign = ({
  type,
  unwrapTypes = KEYS_ALIGN,
  ...props
}) => {
  const editor = useStoreEditorState(useEventEditorId('focus'));
  return /*#__PURE__*/React.createElement(ToolbarButton, _extends({
    active: !!(editor !== null && editor !== void 0 && editor.selection) && !!type && someNode(editor, {
      match: {
        type
      }
    }),
    onMouseDown: editor ? getPreventDefaultHandler(upsertAlign, editor, {
      type,
      unwrapTypes
    }) : undefined
  }, props));
};

Checklist

• The new code matches the existing patterns and styles.
• The tests pass with yarn test.
• The linter passes with yarn lint. (Fix errors with yarn lint --fix.)
• The relevant examples still work: (Run examples with yarn docs.)

Note: running the docs instructions prompted a yarn install which altered the docs/yarn.lock (bumping all packages to 5.3.1). I've left that out of my PR, though
