chore: Upgrades redux

[tuliomir]

This PR upgrades the Redux version of this application from v4 to v5, but instead of keeping it a direct rependency, replaces it with redux-toolkit that indirectly uses redux. This is the strongly recommended approach by the current Redux docs.

This is the first step needed for the broader refactoring of the redux code proposed by #507 , aiming to bring this code to more up to date best practices for Redux.

Acceptance Criteria

• Upgrades the Redux dependency

Security Checklist

• Make sure you do not include new dependencies in the project unless strictly necessary and do not include dev-dependencies as production ones. More dependencies increase the possibility of one of them being hijacked and affecting us.
