Allow to use Pydantic aliases for column names that shadow BaseModel attributes

[D3f0]

Problem

Currently, using a schema like the one bellow will trigger the generator's default dmmf validation preventing using the name schema.

datasource client {
    provider = "sqlite"
    url = "file:db.sqlite"
}
generator client {
  provider             = "prisma-client-py"
  interface            = "asyncio"
  recursive_type_depth = 5
}

model Entity {
  id    Int     @id @default(autoincrement())
  email String  @unique
  schema  String?
}

When running poetry run prisma push

Suggested solution

Create fields with {reserver_name}_ for example, schema_ for the above case, and use Pyndantic aliases.

Alternatives

Create a custom generator.py, but run into problems:

• Creating the dmmf needs the generator's class _on_request to be overridden (assumed to be part of the internal API)
• To enable accept the {reserver_name}_ to {real column} looks like the substitution could go in the class QueryBuilder.get_default_fields, but then again, seems to be part of the internal API, not meant for override.

Additional context

In my use case, the schema file is coming from a TypeScript project and I want to keep compatibility with it without changing the file.
