Renaming optional models also includes `?` in input field, causing trouble

If you then change it to FooBar? as you want to rename it to that and not loose the ?, this is the result:

If you change it to FooBar it does the right thing though - which is also unexpected because the ? was originally part of the input field.

Can reproduce, example

/// multi line
/// commennttt
model Foo {
  id     Int @id
  bar    Bar @relation(fields: [bar_id], references: [id])
  bar_id Int @unique
}

model Bar {
  id  Int  @id
  foo Foo? // rename Foo here
}
