fix: vite related dependabot alerts (#15464)

Resolves [14 Dependabot
Alerts](https://github.com/twentyhq/twenty/security/dependabot?q=is%3Aopen+package%3Avite+manifest%3Ayarn.lock+has%3Apatch)
simultaneously.

Vitest 1.4.0 was imported in root package.json, which further imported
Vite 5. However, Vitest solved no purpose at the moment since we still
rely on Jest for testing. Therefore, removed the package and we can
import the latest 4x version when we move from Jest to Vitest.

For the rest of the use-cases of Vite, ran `yarn up vite --recursive`
for the version used to be greater than 7.0.8.
