Don't create nested folder if useMultipleFiles=false

[oceandrama]

Now, if you are using config like this:

generator zod {
  provider         = "zod-prisma-types"
  output           = "../src/shared/api/zod.ts"
  useMultipleFiles = false //default
}

it creates shared/api/zod.ts folder and index.ts file inside. Maybe it would be simpler to create just shared/api/zod.ts file to reduce nesting

@oceandrama this desicion was made to partly satisfy my OCD and to find specific kinds of types easier. I'don't know if the nesting has any downsides other than the additional folders but for me it seemd to be a bit more structured.
