Fix types compatibility with React 19

[Methuselah96]

Fixes #5911.

React 19 removes the JSX type from the global scope, so it now needs to be imported from React.

This causes some immediate issues for the users of react-select who are trying to use it with @types/react@19, since the Select types relies on the JSX.LibraryManagedAttributes type.

Note that this is technically a breaking change because it requires TypeScript users to have a version of @types/react after https://github.com/DefinitelyTyped/DefinitelyTyped/pull/64464 shipped.
