Ingest: Support bacterial genomes

[joverlee521]

The current NCBI Datasets command in the template is specifically for virus genomes:
https://github.com/nextstrain/pathogen-repo-template/blob/3493a93d48d0fc9bd3bfefb3eab173cbcb5ec382/ingest/rules/fetch_from_ncbi.smk#L72

If you tried to run the command with a bacterial taxon id (e.g. 666 for Vibrio cholerae), the command outputs an error:

The download virus genome taxon command only supports virus taxa.
For data on other organisms, please use the download genome taxon command.

Error: taxa 666 is out of scope

Looking more into the suggested datasets download genome taxon command, which downloads NCBI Dataset Genome Packages.

The data for these genome packages come from the Genome database, which is separate from GenBank. There's a huge difference in the number of records when looking at Vibrio cholerae (6,432 genomes vs 420,006 nucelotides as of 2023-10-11).
