Fix frontend artifacts directory in pyproject.toml (#343)

Fixes an issue where the static directory where the frontend build is
placed was not the one declared explicitly in the `pyproject.toml`. The
frontend build directory was moved from `skore/src/dashboard/static/` to
`skore/src/ui/static` during #325 and the change was not made in
`pyproject.toml`.
