fix: improve binding validation

[liamdebeasi]

Description

The invalid binding detection misses code that is valid JS but is not a valid binding such as export default foo. This PR improves the detection by checking if the code can be used as a binding when passed into babel.

I'm also using the parseCode util now because it has presets that are needed to parse JSX/TSX.
