Subject: [PATCH 1/3] Pin Go to 1.24 in test-pull-request workflow

Go 1.26 introduced breaking changes that prevent zip file creation
for buildpack archives. Pin to Go 1.24 until the issue is resolved.

Subject: [PATCH 2/3] feat: Add cflinuxfs5 to supported stacks

- Add cflinuxfs5 (Ubuntu 24.04) to stack validation in install_go.sh
- Export CF_STACK in package.sh for stack-aware builds

This is a minimal change to unblock cflinuxfs5 testing in dependent
buildpacks. Full cflinuxfs5 dependency support (manifest entries)
will follow in a separate PR once binaries are available.
