Summary:

  Added vg-1.71 to factory/guix-bioinformatics/gn/packages/pangenome.scm immediately after the existing vg
   (v1.72.0). It inherits everything (build phases, native-inputs, inputs, synopsis, description, license,
   properties) and only overrides version and source. The origin must repeat the snippet because
  overriding source replaces the parent's whole origin record.

  - Source: https://github.com/vgteam/vg/releases/download/v1.71.0/vg-v1.71.0.tar.gz
  - sha256: 06ag9gb57wjvmxy4pzvskpkph6i6jvs0vy8rjm1xdk3g76l8vhjb
  - guix package -A '^vg' now lists both vg 1.72.0 and vg 1.71.0.
  - Workshop materials can pin via guix shell vg@1.71.0 or by referencing the vg-1.71 symbol directly from
   a manifest.
