Migrate Vue 2 EOL integration tests to Vue 3

[jamesst20]

Vue 2 being EOL, tests should be upgraded to Vue 3.

• Every packages used for the tests are up to date
• Made no unnecessary edits to the tests
• Tests are pretty close to identical to Vue 2 version
• Updated github workflow

Goal: Give the possibility to drop Vue 2 adapter painlessly. Vue 2 adapter is outdated and preventing update to the latest NodeJS LTS in the workflow.

Visual differences between tests from Vue2 and Vue3

It appears to me the project Inertia is dead and there are no more reasons for me to keep my work open and maintain it.

I am closing all my opened PRs which includes #1864 #1872 #1873 #1874 #1875 #1881

I will be maintaining unofficially my own fork of this library so my projects using Svelte 5 can still live until I find or create an appropriate replacement for this library.

Thanks to everyone who spent time looking at my PRs.

Bummer dude 😕

We've been working really hard on Inertia.js v2.0 (as you can see in Taylor's Laracon keynote), so the project is far from dead — we're just in a bit of an awkward position between major versions.

I apologize that your work has not received more attention, that's partly my fault for not having enough time to review PRs recently. I don't work on Inertia.js full time like other open source maintainers (ie. Laravel, Livewire), so for me it actually requires time out of my personal life. Because of that things just take longer, as much as I wish it didn't.

Thanks for your contributions either way.
