[#97] Update backend and frontend READMEs for naming conventions

This commit involves updating the README.md files for both the backend and
frontend components of the GovTool project. These changes are part of the
ongoing efforts for ticket #85, ensuring that all references to the old 'vva-be'
and 'vva-fe' codenames are replaced with the new 'backend' and 'frontend'
naming convention. This is a continuation of the work done by @adgud, aiming to
maintain consistency across the project's documentation and directory structure.
