[actions] fix WSL tests: properly handle Debian apt sources issue

The Debian WSL image has stale apt sources pointing to ftp.debian.org which no longer hosts bullseye-backports. The previous fix ran sed after the first setup-wsl call, but that call already failed because additional-packages triggers apt-get update internally. For wsl_matrix (Debian, Ubuntu): - Ubuntu: install with additional-packages directly (no apt issue) - Debian: install without packages first, fix sources.list with sed, then run apt-get update/upgrade/install manually with retries - Exclude Debian and Ubuntu-20.04 --lts since node v24+ has exec format errors on WSL1 For wsl_matrix_unofficial (Alpine): - Remove the Debian-specific fix entirely (Alpine uses apk, not apt) See https://github.com/Vampire/setup-wsl/issues/76
