Liam DeBeasi e98620ee99 test(ci): run tests in docker container (#28893)
Issue number: Internal

---------

<!-- 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. -->

The team currently faces two challenges:

1. Verifying visual changes locally is difficult because we cannot use
the existing ground truths as they were generated in Linux environments
and most of our team uses either macOS or Windows. While team members
can generate ground truths in the correct environment, they need to
remember to do that first before making changes.
2. Updating visual diffs is time consuming and can only be done by team
members. Our GitHub Action runs the entire test suite which can take ~10
even if only a handful of screenshots are generated. Additionally, this
job can only be run by team members meaning community contributors
cannot update/add screenshots. This limits them to non-visual tasks when
contributing. In the event that they do want to make visual changes, the
team needs to copy all their code into a branch and manually run
screenshot diffs for them.

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

- This PR introduces the ability to run all Playwright tests inside of a
Docker container using an image with Playwright dependencies. The
container will have access to the local project, so developers can make
changes and then run tests in the container after the changes are
compiled. This enables anyone to propose new screenshot changes.
However, the "update screenshot" job will still be available for folks
who do not want/are unable to use docker.
- There are some typeface differences between GH Actions and the Docker
image which is why there are a handful of screenshots that needed to be
updated.

One risk here is that the Playwright npm and Docker image versions must
be kept in sync. As a result, I also updatRenovate to allow us to auto
update the npm and Docker image versions at the same time.

## Does this introduce a breaking change?

- [ ] Yes
- [x] No

<!--
  If this introduces a breaking change:
1. Describe the impact and migration path for existing applications
below.
  3. Update the BREAKING.md file with the breaking change.
4. Add "BREAKING CHANGE: [...]" to the commit description when merging.

## Other information

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


⚠️ There are still some issues I need to sort out with mounting the
local project on Windows. However, using Ubuntu with the linux subsystem
for windows can be used as a workaround. I'd like to merge this so we
can start testing it in our day-to-day workflow and ironing out any
bugs.
