[3.x] Fix validation errors and connect account form

[joelbutcher]

Updates our version of Login.vue and Register.vue to account for changes made in laravel/jetstream#1123.

Also renames the SocialstreamProviders.vue component to Socialstream.vue and adds the following to the component for displaying Socialstream errors:

<script setup>
import {computed} from 'vue';
import {usePage} from '@inertiajs/inertia-vue3';
import JetInputError from '@/Components/InputError.vue';

const error = computed(() => usePage().props.value.errors.socialstream);
</script>


<template>
  <div>
    // ...

    <JetInputError class="mt-b text-center" :message="error" />
  </div>
</template>
