ci: put java on PATH for the apksigner verify step
Gradle build is green (uses JAVA_HOME directly), but the signer-verify
step calls apksigner — a shell wrapper that needs 'java' on PATH. The
straw-build image sets JAVA_HOME without adding its bin to PATH for run
steps, so apksigner died with 'exec: java: not found'. Export it.

# Straw APK — build on Forgejo Actions, and (gated on a green build) publish to
# fdroid.sulkta.com so the in-app updater picks it up.
#
# Runs in the dedicated git.sulkta.com/sulkta-infra/straw-build image (Android
# SDK/NDK + Rust + cargo-ndk, see ci/Dockerfile). The signing key comes from
# the STRAW_SIGNING_KEYSTORE_B64 secret (the same androiddebugkey the whole
# series is signed with — vaulted as "Sulkta — Straw fdroid signing keystore").
#
# Publish path mirrors scripts/publish-fdroid.sh: drop the APK into the Lucy
# fdroid repo + re-sign the index (both via the host docker socket, keystore
# never leaves Lucy), then stream the signed repo to Rackham web168 over a
# scoped, forced-command deploy key (STRAW_FDROID_RACKHAM_KEY).
