Add react 19

[moshiur01]

The multiselect package is not compatible with React 19.

It works with React 19 as far as I can tell, but the package was not updated in a while.

Add this to your package.json for a workaround:

"overrides": {
   "multiselect-react-dropdown": {
       "react": "^19.0.0"
    }
}
