fix: remove obsolete links from demos/README.md

This commit removes obsolete links to `interactive.chat.sh` and `interactive.generate.sh` from `demos/README.md`.

These scripts were moved to the `apps` directory in a previous commit, but the links in the demos README were not updated. This commit corrects that oversight.
