Add yq to system-tools

[CodeGat]

Closes #10

Background

yq is a useful YAML processor that is used across Gadi for interrogation and manipulation of YAML.

This PR adds yq/spack.yaml, a manifest for the latest yq package using gcc@15.1.0.

Testing

Tested using the prerelease module, and it works fine!

🖥️ Gadi Deployment ✔️

Usage Instructions

yq, defined in yq/spack.yaml, will be deployed to Gadi as:

• 4.45.4 as a Release (when merged).
• pr24-2 as a Prerelease (during this PR).

This Prerelease is accessible on Gadi using:

module use /g/data/vk83/prerelease/modules
module load yq/pr24-2

When using the above modules, the binaries shall be on your $PATH.

For advanced users, this Prerelease is also accessible on Gadi via /g/data/vk83/prerelease/apps/spack/1.1/spack in the yq-pr24-2 environment.
Due to inode-saving measures, one will have to manually untar the environment metadata before environment activation with tar -xf .spack-env .spack-env.tar. It will require one to have write privileges.

Configuration Information

This Prerelease is deployed using:

• access-nri/spack on branch 1.1
• spack/spack-packages version 39aeb9dbcc13b6a53e40c77b672c397e1f4c93ec
• access-nri/access-spack-packages version 2026.02.002
• access-nri/spack-config version 2026.02.001

If the above was not what was expected, commit changes to config/versions.json in this PR, or propose changes to build-cds config/settings.json.

For the rationale for adding a '-RELEASE' build number, see ACCESS-NRI/model-tools#19 (comment)

Can you please add an explanation about the different versions (deployment and model) to the README to document this approach?

[CodeGat]

To which README.md, sorry? 😅
