[@svgr/babel-plugin-transform-svg-component] Fix parsing error of JSX template export statements

[arcticicestudio]

When enabling the ref option the compilation will fail due to a SyntaxError on the unexpected token <:

ERROR in ./src/components/molecules/core/ErrorState404/styled/svg/fragments/space.svg
Module build failed (from ./node_modules/@svgr/webpack/lib/index.js):
SyntaxError: Unexpected token (2:52)
  1 | /* @babel/template */;
> 2 | const ForwardRef = React.forwardRef((props, ref) => <SvgSpace svgRef={ref} {...props} />)
    |                                                    ^
  3 | 
  4 | export default __webpack_public_path__ + "static/space.fea3855e.svg";
  5 | export { ForwardRef as ReactComponent }

This is caused by the util function getExport that creates the JSX export statements.
The root cause is that the Babel's AST template function is called without adding the jsx plugin which results in the unexpected token < which is part of the JSX spec.

To fix the error the jsx plugin has been added to the array of enabled plugins for the Babel AST template.
