Missing / Incorrect Definition

ReadonlyMap<K, V> lacks documentation for forEach, get, has and size.

Hovering these members in an editor shows no description, unlike the corresponding members of Map<K, V>. The documentation should ideally be copied from regular Map<K, V> for consistency, exactly as was done for ReadonlySet<T> in #63481 (fixed by #63483).

Note: the ReadonlyMap members declared in lib.es2015.iterable.d.ts (entries, keys, values and [Symbol.iterator]) are already documented; only the four members declared in lib.es2015.collection.d.ts lack documentation.

Sample Code

declare const m: ReadonlyMap<string, number>;

// Hover any of these: no documentation is shown
m.get("a");
m.has("a");
m.size;
m.forEach(v => console.log(v));
