Support plannetscale database

[chaonengs]

Facts:

• if i use plannetscale, i have to set relationMode = 'prisma' in schema file
• the current verison of prisma in this project does not support relationMode. I have looked the lockfile, it is 4.0.0, to support relationMode, the minimal version of prisma is 4.8.0

Solution:
Maybe update the prisma version? I have tired change the version in package.json, and then run build, but it occured error when building.

I managed to upgradde to prisma 4.15.0 by using @prisma/internals replace of @prisnam/sdk
but the query does not work well, it always return 404 error from the dp server
