[BUG] - Elasticvue uses the old templates API

[aidin-gh]

Description

The Elasticvue is using the deprecated _template API. It should use the new _index_template API.

See: https://www.elastic.co/guide/en/elasticsearch/reference/current/indices-templates-v1.html

Steps To Reproduce

I installed the Firefox extension and checked the developer's console. The network tab shows that it's calling the old API.

I also tried the Linux client. I can't see what API it's calling, but I can check that it doesn't show the templates I have.

Screenshots

Environment (please include the following information):

• Elasticsearch version: 8.14.1

• Browser + version: Firefox 127.0.2
• Elasticvue version: 1.0.8-stable
• How are you running elasticvue? (docker, browser extension, web app): Browser extension & Linux Image
