[bnext-bio, *] Update group folder bindings

[agoose77]

This PR updates the bnext-bio hub to:

1. Reduce copy-and-paste by generating configuration
2. Add new directories for Curvenote and metapure.

I've split the PR into auditable commits:

• 6ca2a08 changes the unique IDs to match what we'll later generate
• 9cc42d5 adds Curvenote under this old schema
• ddf0dd switches to generation
• d2f14ce adds metapure.
• 43ee07c adds metapure & curvenote to login groups, and pulls shared group info from the authenticator.

I have made an assumption that metapure and curvenote teams live under the nucleus-eng org.

@GeorgianaElena you've done much of the work on this hub previously. Are you comfortable with these configuration changes?

This is already in main, but was causing lint failures.

I've replied to Anton, and deployed this to staging. We should hear back with confirmation about merging next week, or I'll just do so on the Monday once we're out of the "engineers are off" danger zone over the weekend!
