Support for Prisma 6

[RubenNL]

Is your feature request related to a problem? Please describe.

Prisma version 6 has been released, which causes this warning:

Looks like an incorrect version "6.0.0" of the Prisma packages has been installed. 'typegraphql-prisma' works only with selected versions, so please ensure that you have installed a version of Prisma that meets the requirement: "^5.18.0". Find out more about that requirement in the docs: https://prisma.typegraphql.com/docs/basics/prisma-version

Bypassing this warning with SKIP_PRISMA_VERSION_CHECK=true works fine for my application, but I don't know if this is the same for everyone.

Describe the solution you'd like

For me, just updating the package.json version should be enough.

Describe alternatives you've considered
