Pull request overview

This PR addresses a sandbox build failure by temporarily disabling the installation of pip.txt requirements in the edxapp deployment playbook. The change comments out the pip.txt file from the requirements installation list, leaving only pip-tools.txt to be installed.

• Modifies the edxapp deployment configuration to skip pip.txt installation
• Retains pip-tools.txt installation to maintain necessary tooling

The commented-out code should be removed entirely rather than left in place. If pip.txt is no longer needed, remove the comment line. Additionally, using with_items for a single item is inefficient - consider removing the with_items loop and directly specifying the requirement file, or explain why this structure is maintained.
