fix(ci): make the test-APK dispatch inputs work and stop it always publishing

Two defects in a workflow that had never actually run.

The publish guard was `if: ${{ inputs.publish }}`. A dispatch input arrives
as a *string*, and every non-empty string is truthy in the expression
language, so "false" is truthy too -- the workflow would have published a
public pre-release on every run, including the ones where the box was
deliberately left unticked. Now compared against 'true' explicitly.

The bare `inputs.*` context is also newer than `github.event.inputs.*` and
no other workflow here uses either, so nothing proved the short form works
on this Gitea. Switched to the form both Gitea and GitHub have supported
throughout; an unresolved context would have silently expanded to an empty
string, sending every build down the `debug` branch and then failing to
find a `*-debug.apk`.
