[BUG] Async-Search in OS 3.0

[Tokesh]

What is the bug?
Hello everyone!
I wrote specs for async-search in OpenSearch-api-specification repo
We test all our PRs in different versions of OpenSearch.
So, as i understand, async-search is already available in OS 3.0, but i cant find a tag that i can use.
I tried using the latest tag, but it doesnt work.
Do I understand correctly that async search should be in version 3.0?

How can one reproduce the bug?
use async-search APIs with latest tag of OS 3.0
mostly i got [INFO] <= 400 (application/json) | "no handler found for uri [/_plugins/_asynchronous_search] and method [POST]"

What is the expected behavior?
It should work in 3.0 the same as in 2.x, or its bug

What is your host/environment?
Docker CI configs

• OS: Ubuntu
• Version 22.04
• Plugins

Do you have any additional context?
I'm newbie at this repo. I’m always happy to make new connections and meet friendly people here. You can ask me any questions, I will try to answer as quickly as possible and my colleagues from our repository.
