mySQL8: Unknown authentication plugin `sha256_password'

Bug description

Trying to pull the schema (and I assume later querying) yields this with a vanilla mysql8 install:

Introspecting based on datasource defined in prisma/schema.prisma …
Error: Error in connector: Error querying the database: Error querying the database: Error querying the database: Unknown authentication plugin `sha256_password'.

It’s the same issue that plagues the mysql vs mysql2 npm package, ever since mysql’s default changed, downgrading auth is not a solution.

How to reproduce

1. run npx prisma db pull on a mysql8 install

Expected behavior

No response

Prisma information

All default as per prisma.io docs. Examples included, but actual connection details censored.

DATABASE_URL="mysql://root:randompassword@localhost:3306/mydb"

  provider = "mysql"
  url      = env("DATABASE_URL")
}

generator client {
  provider = "prisma-client-js"
}

I also faced this issue. I solved the issue by correcting a wrong DB user name in the config.

No, worries. Do let me know if this somehow happens again.
