🐛 Incorrect formatting inside mapped keys

[ematipico]

Environment information

main

What happened?

At the moment, we slightly differ when formatting mapped keys

Us

export type OmitIndexSignature<ObjectType> = {
  [KeyType in
    keyof ObjectType as {} extends Record<KeyType, unknown>
      ? never
      : KeyType]: ObjectType[KeyType];
};

Them

export type OmitIndexSignature<ObjectType> = {
  [KeyType in keyof ObjectType as {} extends Record<KeyType, unknown>
    ? never
    : KeyType]: ObjectType[KeyType];
};

Expected result

It shouldn't differ
