fix(scripts): make client build compatible with Bash 3.2 (macOS) (#7332)

* fix(scripts): make client build compatible with Bash 3.2 (macOS)

I started poking around here earlier this morning, to build and run tests and contribute something, but I quickly ran into the problem with Bash 4 requirements as I'm on MacOS. I was thinking this might pose an overly high barrier to entry for newcomers. Beautiful with the Bash 4+ associative arrays, but being able to check out the project and just run `npm run build` after the necessary Homebrew Node/npm/FFmpeg installs that's also beautiful! :)))

* refactor(scripts): use `key:locale` pairs instead of parallel arrays

Address maintainer feedback https://github.com/Chocobozzz/PeerTube/pull/7332#issuecomment-3646366574, keep the association between key and value visible by using "key:locale" pairs in a single array, with one language per line for easy scanning.
