ci: consistently use latest cache-apt-pkgs-action for ffmpeg

[joanise]

PR Goal?

FedericoCarboni is an unstable way to install ffmpeg on Linux. awalsh128/cache-apt-pkgs-action, on the other hand, is fast and (mostly) reliable, with a small bug fix to make it work consistently.

Instead of trying one way, which sometimes fails, and then trying a second slower way, let's always use the reliable apt install, with caching to make it fast (most of the time, i.e., on cache hits).

Also bump cache-apt-pkgs-action to the latest version with node 24 in sub actions--it was actually this bump to threw me down the rabbit hole, with CI failing is weird and unexpected ways.

Fixes?

Speed and reliability of ffmpeg installation in CI

Feedback sought?

please review my updated workflow carefully, though I'm quite confident

Priority?

normal

Tests added?

it's just for testing

How to test?

see CI pass more reliably and faster than before

Confidence?

pretty high

Version change?

no
