test: install matching Chromium in e2e playwright Dockerfile

The base image's pre-installed Chromium can lag behind a newer Playwright
pulled via crawlee[playwright], breaking browser launch with "Executable
doesn't exist". Run `playwright install chromium` after the pip
force-reinstall so the binary always matches the installed Playwright.
