Provide a clear and concise overview of the new feature requested.

This is a checklist of documentation updates needed for 14.5.0.

• Add description for new Cloud-J v8 YAML tags to geoschem-config.rst
• Migrate the following pages to the https://github.com/geoschem/geos-chem-shared-docs repo, as these are used for both GCClassic and GCHP:
  • geoschem-config.rst
  • hemco-config.rst
  • hemco-diagn.rst
• Replace the "Download input data" page with the updated page by Yidan in geos-chem-shared-docs (when the WashU S3 bucket goes online)
• Test the instructions in Build required software with Spack to make sure that they still work (or if a Spack update has broken the workflow).
• Feel free to add others
