Script to create main release static content

[leannehaggerty]

Currently works for the creating the new general vertebrate static content, i.e. content outlined here https://docs.google.com/document/d/1oaEVACrM_J4WruJragbpNUC8h8qjUxbh6q90_FXpMuY/edit?tab=t.0#heading=h.g9et3sgf9qa7

Note:

• This is not the agreed content for the mouse strains, the script should be updated for that

It is fine for me but I will leave the final approving on the metadata to Jose.
Thanks!

Tested for cow and cat and works fine for both.

Looks good to me.

Oh, there was some talk about creating a pre-requisites.txt, so I'll delay merging until that.

Can you take a look at the adaptation and re-approve, @leannehaggerty?
Mentioning also @ens-ftricomi for continuity.

I made changes and can't review myself.
