 * Checks whether the MutableHashMap contains the specified key.
 *
 * **When to use**
 *
 * Use to test whether a key is present in a `MutableHashMap` without reading
 * its value.
 *
 * **Example** (Checking for a key)
 *
 * ```ts import.meta.vitest
 * import { MutableHashMap } from "effect"
 *
 * const map = MutableHashMap.make(["key1", 42], ["key2", 100])
 *
 * MutableHashMap.has(map, "key1") // => true
 * MutableHashMap.has(map, "key3") // => false
 *
 * // Pipe-able version
 * MutableHashMap.has("key1")(map) // => true
