fix(linux): Fix GHA package build

feat(linux): Implement uploading of packages in packaging GHA

feat(linux): Pass PR# in the event type

auto: increment master version to 17.0.49

This allows to see which GHA build ran on which branch/PR.

fix(linux): Fix path to symbols file in packaging GHA

chore(linux): Exclude autopkg tests on s390x 🍒

chore(common): Report status if no platform needs build

docs(linux): Update packaging documentation

We don't build the binaries on s390x so it doesn't make sense trying
to run the autopkg tests on s390x. This change imports the changes
made on Debian in pkg version 16.0.138-4.

chore(common): automatically apply _builder_check_color

fix(developer): Select BCP47 Code dialog inconsistencies

auto: increment master version to 17.0.48

We need to use HEAD of the PR for setting the status, not the
merge commit.

This works around a problem where status.keyman.com keeps a PR in
the "Waiting for build" status because no status messages appear
in the PR because no files changed that affect any platform (e.g.
changes in GHA or documentation) which causes no platform builds
to be triggered.

fix(linux): Fix Verify-API step of GHA

fix(linux): Fix autopkgtests 🍒

auto: increment master version to 17.0.47

- remove obsolete `packageName` variable
- add section on how to build with Docker, similar to how the
  package build is done on GHA
- updated "uploading to Debian" section
- some reformatting

We need to specify the full ref, otherwise GitHub will add
`refs/heads` and `refs/tags` which won't work for pull requests.
