GHA: tidy up apt commands

- drop `--quiet 2` option where used, to have uniform output.
- replace `apt` with `apt-get` in one job. sync options with rest.
- replace deprecated `apt-key` command with the alternative recommended
  by `apt-key(8)`.
- drop stray `cd /tmp`, no longer needed after migrating to GHA.
- shorten `--option Dpkg::Use-Pty=0` to `-o Dpkg::Use-Pty=0`.
- add `-o Dpkg::Use-Pty=0` to hide `apt-get` progress bars taking
  vertical log space, where missing.
- drop `-y --no-install-suggests --no-install-recommends` `apt-get`
  options. They are the default in the ubuntu-24.04 image.
- GHA/distcheck: move `name:` to top in steps where not there.
- scripts/cijobs.pl: catch `apt-get` lines with the `-o` option.

Closes #16127
