Error classes are wrapped twice

[janpio]

Client error messages always include the exception type twice, one with an added 2 at the end:

PrismaClientInitializationError2 [PrismaClientInitializationError]: 
Invalid `prisma.user.create()` invocation:
...

This does not seem to be intended and should be fixed.

That comes from esbuild
It means that we’re for whatever reason probably bundling the runtime twice
So someone would need to debug the esbuild output

This got worse along the way, we are now up to PrismaClientInitializationError3 (see #8836)

Also effects other error types now: PrismaClientKnownRequestError3 [PrismaClientKnownRequestError] (via #8839 (comment))
