Bug description

Running the prisma format command on a directory with a schema.prisma file and a model.schema file will only cause the schema.prisma file to be formatted. The CLI allows a --schema flag to point to a schema file but doing so with the prismaSchemaFolder preview feature enabled causes it to error as the native database types found from the datasource provider in schema.prisma is not used.

How to reproduce

• Create a Prisma schema folder.
• Enable prismaSchemaFolder preview feature.
• Run prisma format on the schema folder.
• Run prisma format --schema=<model schema> to format a model file.

Expected behavior

This should ideally format all valid schema files when under a schema folder or at least auto detect the datasource provider.

}

    id String @id @db.String(12)
