chore(visual-regression): add script to update ground truths (#29204)

Issue number: N/A

---------

<!-- Please do not submit updates to dependencies unless it fixes an
issue. -->

<!-- Please try to limit your pull request to one type (bugfix, feature,
etc). Submit multiple pull requests if needed. -->

## What is the current behavior?
<!-- Please describe the current behavior that you are modifying. -->

Devs would have to manually generate the ground truths from their
desired base branch. This causes a dev to checkout the base branch and
pull the latest screenshots. They would then return to their working
branch and start the E2E tests.

## What is the new behavior?
<!-- Please describe the behavior or changes that are being added by
this PR. -->

A script has been created to automate this process using Docker as
mentioned in the design doc:

- It will ask the user a set a questions like if which component they
want to test


## Does this introduce a breaking change?

- [ ] Yes
- [x] No

<!--

## Other information

<!-- Any other information that is important to this PR such as
screenshots of how the component looks before and after the change. -->

How to test:
1. Make a change to a desired component
2. Run `npm run test.e2e.script`
3. Answer the questions
4. Verify that the tests fail due to visual changes
5. Re-run the command as many times as necessary in order to try
different routes based on different answers
