[#97] Update local domain names for backend and frontend services in …

…docker compose

This commit changes the local domain names for the backend and frontend services
in the docker-compose.yml file, as part of the initiative in ticket #85. The
modification is aimed at aligning the local development environment with the
new backend/frontend naming convention. By updating the domain names, we ensure
that the local URLs used for accessing these services reflect the updated
project structure and naming standards.

Technical Details:
- Updated the Traefik router rule for the backend service. The local domain
  name is changed from `vva-be.localhost` to `backend-govtool.localhost`. This
  alteration is specified in the label `traefik.http.routers.backend.rule`.
- For the frontend service, updated the Traefik router rule to change its
  local domain from `vva-fe.localhost` to `frontend-govtool.localhost`. This
  change is reflected in the label `traefik.http.routers.frontend.rule`.
