Feature: Migrate to GA4

**Community discussion about this feature (mandatory)**
Discussed with c2c board and developpers

**Is your feature request related to a problem? Please describe.**
Google Analystics is no long working. We should use GA4.

**Describe the solution you'd like**
This code should be integreted so that it should be use on all topoguide pages
```

window.dataLayer = window.dataLayer || [];
function gtag(){dataLayer.push(arguments);}
gtag('js', new Date());

gtag('config', 'G-YEVSKTFH2Q');

```

**Describe alternatives you've considered**
[vue-gtatg](https://github.com/MatteoGabriele/vue-gtag) is a vue plugin for GA4. We considered use it instead of the one currently used ([vueanalytics](https://www.npmjs.com/package/vue-analytics)), but vue-gtag required vue 3.0.0 and there are a lot of plugins we used that are not ready for vue 3.0.0

Start by locating the existing vueanalytics integration and the topoguide page entry points. Compare the current setup with the proposed GA4 gtag.js snippet or vue-gtag alternative, then verify that GA4 is integrated across all topoguide pages without requiring Vue 3.
