Create test-deploy.yml (#161)

* Create test-deploy.yml

Adding gh action workflow that will be triggered for every PR if the changes happen in website directory.

Note: The code changes outside of website directory on main branch won't go through this check.

The changes will be tested with `yarn build` command to make sure the changes don't break the existing docs.

* Update and rename test-deploy.yml to site-test.yml

* Rename file, update refs and use cache from setup-node

* Test commit
