Allow devDependencies prop inside of customSetup object

Tell us how you think we can improve Sandpack

Packages affected

• sandpack-client
• sandpack-react

What is this feature?

Allow users to pass a devDependencies object similar to dependencies with is supported by the customSetup object

Motivation for this feature

• Sometimes a user is using npm packages that don't have typescript types bundled with the library, so a user has to go to find the @types/... packages on npm
• sometimes a user might want to open a sandpack preview with the "open in codesanbox" button and when they load the package, they might see lots of red warnings because types are missing

From a user perspective, my first reaction to seeing that devDependencies wasn't allowed as a prop is: Why? so i think other might also have that reaction too, perhaps they haven't voiced it and spent the time to write about it on here
