refactor(templates): use Vue CLI for 2.x.x

[samouss]

This PR updates the template for Vue InstantSearch 2.x.x with Vue CLI.

I've update the .eslintrc.js to disable two rules that conflict each other (until we fix the Algolia one):

• extends from prettier/vue
• use kebab-case for vue/component-name-in-template-casing

[Haroenv]

it works as expected

I've been meaning to update this template for a while. Thanks for tackling it!

The app is terribly lagging on my machine. Are you experiencing the same thing?

Why did you remove manifest.json?

I would be in favor of also updating the Vue InstantSearch v2 template to have the same setup and to reduce Renovate noise.

manifest.json is removed because Vue CLI no longer generates it I think

Nope, I've also uploaded it to CodeSandbox and I don't have the issue.

Why did you remove manifest.json?

Yep @Haroenv is correct, it's only generated with the PWA plugin enabled.

I tried the template again this morning and it seems to work better than yesterday. Probably my machine's fault.

We can update the Vue InstantSearch v1 template in another PR.
