This patch:
- removes the Visual Regression bits from the images. These will
probably be added back when it's ready for the prime time.
* removes VNC && noVNC
* removes Playwright Agent
- cleans up apt caches
This drops image size from 2.03GB to 1.91GB.
Turns out Azure Pipelines is doing a few modifications to the base
container. One of the important modification is that they add a new
user to the container that has a passwordless sudo permissions. This
user is used later on to run all the pipeline steps.
This patch makes sure our shared registry inside the docker containers
is accessible to all the users.
Fixes#5635
Instead of symlinking pwuser's registry to root's registry, we now
use the `PLAYWRIGHT_BROWSERS_PATH` variable to define a single
browser registry across the docker image, accessible for all
users.
Fixes#4485
