Description

Currently, the JavaScript admin client exposes all its internals publically, meaning that is leaking private APIs that we now have to commit to as a public API in terms of stability. For example, when importing type definitions, a path that deeply accesses the package contents is used:

import type UserRepresentation from "@keycloak/keycloak-admin-client/lib/defs/userRepresentation.js";

The package should add all explicitly exported parts of the API surface to a single index file, and use the exports field of the package to define it, so no other parts of the API are leaked:

{
    "name": "@keycloak/keycloak-admin-client",
    "type": "module",
    "exports": {
        ".": {
           "types": "./lib/index.d.ts",
            "default": "./lib/index.js"
        }
    }
}

This will allow us to make breaking changes on internal APIs, without violating the API public stability contract with the consumers of the library.
