Type hint mismatch

[NoahTheDuke]

In collection.clj, insert, find, etc all hint coll as a String: [^DB db ^String coll] even tho their implementation calls name on the coll. Clojure doesn't use this type hint to change the actual implementation, but clj-kondo uses them to throw linting errors.

Given that (mg/find-one db :example {}) works, I'd like to not have any linting errors due to mismatched types. I'm willing to open a PR for this if y'all are amenable.
