update to new auth core version

[Tricked-dev]

This fixed various issues for me so i thought why not pull request it back i changed the auth route from /api/auth to just /auth :0 this is what sveltekit auth does too

install: (& run npm/bun/pnpm/yarn/(whatever new npm package manager) install)

{
 "dependencies": {
    "auth-astro": "git+https://github.com/Tricked-dev/auth-astro.git"
}
