tools: Upgrade Playwright

Upgrade Playwright to latest version and slightly updated upgrade docs again
to use node with `--prefix` flag like we did in the previous commit.
Like documented, we ran

    npx --prefix e2e -y npm-check-updates --packageFile e2e/package.json -u
    npm --prefix e2e install
    npx --prefix e2e playwright install

manually upgraded the Docker image used in the Makefile and manually tested
the upgrade with `make e2e USE_DOCKER=1`.
