chore: install JDK via .tool-versions (#10663)

For working on the Android app, we need an installation of the JDK.
Currently, that is being installed separately in CI. We already have
`.tool-versions` which is designed to take care of this so we add
OpenJDK 17 to the list of required tools and remove the dedicated CI
step.
