[actions] expand NCBI builds to cattle-flu & d1.1

[jameshadfield]

Previously the only NCBI build was the 'h5n1-cattle-outbreak.yaml'.

Note that future work will hopefully combine these two (sets of) builds into a single config YAML, however we'll still want to incorporate the ability to toggle between the different targets in the action.

Needs testing

[jameshadfield]

Testing:

• Manual run of the "Phylogenetic NCBI" workflow for D1.1 successfully completed
• Manual run of the "Phylogenetic NCBI" workflow for cattle-outbreak successfully completed, although note discussion points in this PR.
  • I ran this again to verify the sumary-step fixes and then cancelled the workflow once the summary had been generated
• Ingest to phylogenetic - do we need to test this before merging, or is a review enough?

LGTM, seems fine to merge after the open discussions are resolved.
