Use opensearch-builds CI runner for functional tests

[ashwin-pc]

Is your feature request related to a problem? Please describe.

Currently we use ubuntu-latest runner for our functional tests. because of this we need to manually install the chromedriver npm package to run our functional tests. This package is not always up to date with the latest chrome driver version causing functional test failures in the repo. We already have a runner with all the necessary packages installed in opensearch-build

Describe the solution you'd like

Use the ci runner instead of the default github runner

Describe alternatives you've considered

using a patch version of the chrome driver. This is not ideal because it will still require us to be dependent on the chromedriver npm package in future

I have it running in the container in this PR #1624 but unfortunately. the user github uses is 1001 and the docker image dumps most of the setup stuff in a folder that isn't just a regular user.

In multiple attempts I tried to have the runner point do work in that expected directory but github actions has verification steps that don't quite make sense to me [link to issue].

So for the time being, the PR I listed above lets us control the chromedriver version and we wont be surprised as much as other as relying on github envs.
