feat: Use vitest instead of jest, run all the specs anywhere in app/ folder in the CI (#9722)

Due to the pattern `**/specs/*.spec.js` defined in CircleCI, none of the
frontend spec in the folders such as
`specs/<domain-name>/getters.spec.js` were not executed in Circle CI.

This PR fixes the issue, along with the following changes: 
- Use vitest instead of jest
- Remove jest dependancies
- Update tests to work with vitest
