Use correct extra_deps_from_github.txt file path in setup.sh

[bvandermoon]

Description

setup.sh was updated in #2541 as part of the ongoing restructuring effort. @NuojCheng saw an error when running bash setup.sh after this change:

Installing "tpu-requirements.txt" with pinned commits.
error: File not found: `dependencies/requirements/extra_deps_from_github.txt

This PR points the setup script to the correct file location

Tests

• Reproduced the error on main with bash tools/setup/setup.sh and bash tools/setup/setup.sh MODE=nightly
• Re-ran both commands on this branch and the script finished successfully
