This adds a new script to calculate docker image size with all parent layers. Note: take this metrics with a grain of salt, since in reality docker compresses and reuses layers. Some historic stats obtained with this script: - **`208MB`** (-33MB) chore(docker): skip "recommended" dependencies (#2917) (1cebf8757c) - **`241MB`** (-29MB) chore(docker): trim some of the gstreamer dependencies (#2897) (bce4b1aea9) - **`272MB`** (-1MB) devops: do cache busting for APT (#2656) (bb34418095) - **`273MB`** (+49MB) fix(webkit): update Docker file to include gstreamer (#2636) (5c6c65915c) - **`224MB`** (+0MB) chore: fix emojis for CR and FF in Dockerfile (#2522) (24316ad261) - **`224MB`** (-1MB) fix: Dockerfile for Firefox (#1937) (b516ac4fb2) - **`225MB`** (+49MB) devops(docker): Install ffmpeg dependency, adding codecs necessary for video playback in Firefox (#1627) (222d01caaa) - **`176MB`** (+32MB) chore(docs): optionally install XVFB in docker(ec3ee66043) - **`144MB`** (+144MB) feat: add a playwright-ready docker image (#1161)(1781ae7006)
