Add SSR support and enhance Vue integration for Tolgee

[EugeneBalabai]

This PR improves the Tolgee integration with Vue, focusing on enhancing Server-Side Rendering (SSR) support and overall functionality. Key changes include:

• Refactored the TolgeeProvider component to handle SSR scenarios.
• Improved the useTolgee hook to better handle reactivity and event listeners.
• Updated the T component to respect the initial render state for SSR.
• Streamlined the VueTolgee plugin to provide better support for SSR.

These changes aim to provide a more robust integration of Tolgee with Vue applications, especially in SSR environments. The updates should result in improved performance and developer experience when working with translations in Vue projects.

Would you be able to also write some short documentation? Something like this https://tolgee.io/js-sdk/integrations/react/ssr . If you don't have time, I can do it, but we need some docs for this.

I will try to do it this evening. In general, I think we can copy most parts of the React documentation and just adjust the syntax, because for Vue we don't have useTolgeeSSR but the main logic is the same.

Hey @stepan662,
I've attached a draft of the documentation. I've incorporated most parts from the React SSR documentation. Please feel free to adjust and publish it.

Additionally, I think it would be a good idea to add an example of integration for Nuxt. We should also mention the version of Tolgee that supports Vue SSR.

Yeah the example for nuxt would be really cool. I'm currently stuck on a big task in the platform, so I can do it later, if you don't have time to do it.
