Top-level LAST_TOLGEE_INSTANCE disables previous instance

[jvruss]

I have multiple widgets injected into the main project. Each widget is wrapped in a TolgeeProvider with its own TolgeeInstance. The main project is also wrapped and uses useSuspense to dynamically load translations by routes.

tolgee-js/packages/react/src/TolgeeProvider.tsx

Line 22 in d8424b3

let LAST_TOLGEE_INSTANCE: TolgeeInstance | undefined = undefined;

Since LAST_TOLGEE_INSTANCE is defined at the top level, each new provider render overrides the previous one, stopping translations from loading
