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.

(cherry picked from commit 69a4a61b)

chore(windows): Fix Portuguese UI language name

chore(common): Cleanup Kannada locale

fix(linux): Fix autopkgtests 🍒

Fixes the scenario where `builder_describe_outputs` is called after
`builder_parse`, so that internal dependencies will be built as
required.

chore(ios): update certificate

The id node taken from the keyman_keyboardlist.xsl was using the
packgage id name rather than the keyboard id name. This change
corrects that.

auto: increment master version to 17.0.45

Autopkgtests couldn't find pkg-config, so this change adds that as
test dependency.
