fix(web): move @headlessui/react to react-vendor chunk (#65)

* fix(web): move @headlessui/react to react-vendor chunk

@headlessui/react uses React.forwardRef internally. When it was in a
separate ui-vendor chunk, browsers could load it before react-vendor
in production, causing "Cannot read properties of undefined (reading
'forwardRef')" errors.

Moving @headlessui/react to the same chunk as React ensures it's always
loaded after React is available.
