Optimize image size

[mglaman]

The following step isn't reducing the layer sizes:

RUN apt-get clean && \
    rm -rf /var/lib/apt/lists/* \
    /tmp/* \
    /var/tmp/* \
    /usr/share/doc/* \
    /usr/share/man/*

This layer is 265MB

# Install Node.js 24 (includes npm)
RUN curl -fsSL https://deb.nodesource.com/setup_24.x | bash - && \
    apt-get install -y --no-install-recommends nodejs

We could copy the binaries from a Node image using

FROM node:24 as node
ENV npm_config_ignore_scripts=true
ENV YARN_ENABLE_SCRIPTS=false

FROM php:8.3-apache AS base

COPY --from=node /usr/local/bin /usr/local/bin
COPY --from=node /usr/local/lib/node_modules /usr/local/lib/node_modules

We should clean up in this same layer as well. It's 802MB, not sure how much it can be trimmed down.

# Install Playwright OS dependencies.
RUN npx playwright install-deps

Actually I think we should restructure this:

# Used for PHPUnit functional tests.
RUN CHROME_VERSION=$(curl -s https://googlechromelabs.github.io/chrome-for-testing/last-known-good-versions-with-downloads.json | jq -r '.channels.Stable.version') && \

# Install Playwright OS dependencies.
RUN npx playwright install-deps && \
	date > /tmp/cache-bust && npx playwright install --with-deps && \
	&& apt-get clean && \
    rm -rf /var/lib/apt/lists/

Actually, isn't npx playwright install-deps not needed due to --with-deps
