Hello again isaac!

Today, I found a type bug in node-glob. The following code results in a type error:

const MY_IGNORES = ["foo", "bar"] as const;
await glob("**/*.txt, {
  ignore: MY_IGNORES,
})

This PR fixes the bug. Note that this change is backwards compatible because in TypeScript, you don't have to do readonly string[] | string[], because readonly string[] is the superset of both these things due to how the type system works.

Furthermore, the same issue seems to be present in the codebase in other places:

• All  glob* , stream, and iterate functions in  src/index.ts 
• new Glob(pattern, options)  in  src/glob.ts 
• hasMagic(pattern)  in  src/has-magic.ts

Do you want me to fix those too?
