Console core package: Convert components in cluster-settings folder from class component to functional component

One of the steps of the migration strategy is start using the v6 API for components that are passed to the `CompatRoute` component, based on the [migration strategy guide|https://github.com/remix-run/react-router/discussions/8753.]. This route now has both v5 and v6 routing contexts, so we can start migrating component code to v6.

If the component is a class component, you'll need to convert it to a function component first so that you can use hooks.

The following files in frontend/public/components/cluster-settings contain components that need to use the v6 useNavigate hook, requiring them to be converted from a class component to a functional component: 

• basicauth-idp-form.tsx
• github-idp-form.tsx
• gitlab-idp-form.tsx
• google-idp-form.tsx
• htpasswd-idp-form.tsx
• keystone-idp-form.tsx
• idap-idp-form.tsx
• openid-idp-form.tsx
• request-header-idp-form.tsx
