GitHubCI: fix all Linux issues about interactive installs

This error was spotted in linux22-vanilla--stockmono-only:

```
Setting up tzdata (2025b-0ubuntu0.22.04.1) ...
debconf: unable to initialize frontend: Dialog
debconf: (Dialog frontend will not work on a dumb terminal, an emacs shell buffer, or without a controlling terminal.)
debconf: falling back to frontend: Readline
Configuring tzdata
------------------

Please select the geographic area in which you live. Subsequent configuration
questions will narrow this down by presenting a list of cities, representing
the time zones in which they are located.

  1. Africa      4. Australia  7. Atlantic  10. Pacific  13. Legacy
  2. America     5. Arctic     8. Europe    11. US
  3. Antarctica  6. Asia       9. Indian    12. Etc
context canceled
Geographic area:
```

Which led to the job hang, and be cancelled hours later. Now
we use the DEBIAN_FRONTEND= workaround everywhere to fix this.
