Incompatible with React 19

[daniharo]

This library makes use of React.__SECRET_INTERNALS_DO_NOT_USE_OR_YOU_WILL_BE_FIRED.ReactCurrentOwner, which is removed in React 19.

Therefore, when trying to use it with React 19, you get "TypeError: Cannot read properties of undefined (reading 'ReactCurrentOwner')".

Reproduction: https://codesandbox.io/p/sandbox/fluentui-react-components-with-react-19-g4g5pw?file=%2Fsrc%2FApp.tsx

The error happens here:

use-disposable/src/useIsStrictMode.ts

Lines 6 to 9 in 3e3d4a3

	export const getCurrentOwner = () =>
	// @ts-ignore - using react internals
	React.__SECRET_INTERNALS_DO_NOT_USE_OR_YOU_WILL_BE_FIRED.ReactCurrentOwner
	.current;

#32 should fix the throwing in React 19. However, there are still two tests that fail due to effect ordring differences. Will need to look further there

Seems that Next.js with their canary versions is also affected, microsoft/fluentui#31930.
