Replace fetch-from-biosample with NCBI Datasets output

[joverlee521]

The fetch-from-biosample script was added before we fully transitioned to using the NCBI Datasets CLI.

Today I noticed in the NCBI Datasets CLI docs for the datasets download virus genome command that you can request to include the biosample report as part of the download with --include biosample.

I cannot find any official reference documentation on the schema of the biosample report, so will just have to try out the download and compare it to the output of the original fetch-from-biosample report.
