Running Playwright (or the stack) in Docker

[andrecasal]

Running visual regression tests on macOS saves the snapshots as *-chromium-darwin.png. During deployment they are compared to *-chromium-linux.png, so all visual regression tests fail.

Would be nice to have Playwright (or the stack) run in the same environment in both cases, to solve problems like this.

could this be fixed by just documentation, in the spirit of #662 ? You will need ofc to add the -v flag to attach a volume.
I personally prefer to run the apps I develop on my machine and not in docker containers. this includes tests, dev server.. (that's why I put a thumbs down)
