Export a Prisma middleware

[lforst]

Having an integration to instrument Prisma is probably not the best idea as shown in #8383

It's probably a good idea to have a simple Prisma middleware we export that is "immune" to weird multi-instrumentation issues.

FYI middleware is getting deprecated: https://www.prisma.io/docs/concepts/components/prisma-client/middleware, but still in favor of less magical instrumentation here, perhaps playing nicely with prisma's builtin tracing feature would be best.

@Blitz2145 Thanks for letting us know. The clientExtensions are actually kinda dope because they let us inspect the queries directly (Which should lead to way better instrumentation)!

So given we now have https://github.com/getsentry/sentry-javascript/blob/develop/packages/node/src/integrations/tracing/prisma.ts I'm going to close this, but we can re-visit!
