Schema folder support.

[Blankeos]

Hi! Is this supported yet? It's in the v5.15 of Prisma: https://www.prisma.io/blog/organize-your-prisma-schema-with-multi-file-support. Currently, the latest version of Prisma is 6.2.1.

I noticed that the prisma version from the cargo CLI isn't really above 4.8.0 though.

I also couldn't find anything in the docs mentioning that prisma-client-rust only supports lower versions of Prisma. Maybe if it isn't, can this be mentioned?
