feat(index): support isolated index in Vue

[Haroenv]

What

Adds an isolated prop to Vue's <ais-index> (AisIndex), threading it through to the index widget's isolated option (graduated from EXPERIMENTAL_isolated in #7117). This brings Vue to parity with JS and React, which already expose isolated.

• indexName is no longer required on <ais-index>, since isolated indices don't need one. The underlying index widget already validates that either indexName or isolated is provided.
• Vue never shipped the experimental EXPERIMENTAL_isolated, so only the stable isolated prop is exposed — no deprecated alias is needed (unlike JS/React, which kept aliases for their previously-shipped experimental names).

Test plan

• yarn jest packages/vue-instantsearch/src/components/__tests__/Index.js — added a test asserting isolated: true is passed to widgetParams without an indexName.
• Full vue-instantsearch suite green on Vue 2 and Vue 3.

Draft: opening early for review of the API shape.
