When running darklua process, trailing commas in types are stripped even if no rules are enabled. This occurs in DarkLua v0.16.0.

You can demonstrate this by making a simple file that contains types with trailing commas:

type Foo = {
  key1: Type1,
  key2: Type2,
}

and processing it with no rules (a config like {"rules":[]}) results in:

type Foo = {
  key1: Type1,
  key2: Type2
}
