Feature Request: Improve docs discoverability for older Prisma versions

[Hephaest]

Hi team,

I’m currently onboarding to a project that uses Prisma v6 in production.

I’m finding it difficult to understand our current repo’s configuration and implementation when I read the latest (v7) documentation. A lot of examples and options don’t match what I see in our codebase.

Right now, the only reliable way I’ve found to self-onboard is:

1. Clone this repo
2. Trace Git history back to the commit right before it is upgraded to v7
3. Try to infer how things used to work from there

It would be more helpful if there were an easier way to find documentation for older major versions (like v6), especially for onboarding and maintaining existing projects.
