Search: Add e2e tests

[rebeccahum]

Description

This PR adds the e2e tests via Cypress from upstream. However, there has been several modifications to make it work with vip-go-mu-plugins + VIP Search, so it will definitely not be 1:1.

Next step is to add it to our ci/cd pipeline.

Steps to Test

1. npm i
2. npm run search-build
3. npm run search-env:start
4. npm run cypress:setup
5. npm run cypress:run:

[sjinks]

@rebeccahum do we want to run these tests as a part of our CI process?

[rebeccahum]

@sjinks Yes, I just wanted to get it in the repo first and then I'll open a PR for the CI process.
