[ENH] Provide Apptainer .def file as reference

[36000]

Previously, we had a def file for installing GPUstreamlines the old system and installing pyAFQ from a local repo into apptainer. This updates to the new GPUstreamlines and updates to install pyAFQ from main, which I think will be more generally useful.

Pull request overview

This pull request replaces the placeholder-based Apptainer build system with a simplified reference definition file for building pyAFQ GPU containers. The old approach required a build script to substitute placeholders, while the new approach provides a straightforward, self-contained definition file.

Changes:

• Removed cuda_track_template.def and its associated build script cuda_build.sh
• Added pyafq_with_gpu_template.def as a reference Apptainer definition file that installs pyAFQ directly from GitHub

File	Description
gpu_docker/pyafq_with_gpu_template.def	New simplified Apptainer definition file for GPU-enabled pyAFQ installation

gpu_docker/cuda_track_template.def:1

• The file cuda_track_template.def is referenced in the documentation at docs/source/howto/singularity.rst line 9. Removing this file without updating the documentation will create a broken link. The documentation should be updated to reference the new pyafq_with_gpu_template.def file instead.
