fix(scripts): always exit 0 from check-aws-updates.py

The script was returning exit code 1 when updates were found, which
caused the GitHub Actions workflow to fail at that step, preventing
subsequent steps from executing (commit tracking, issue creation,
summary).

The script correctly sets output variables (updates_found, update_count)
to communicate results, but the non-zero exit code halted the workflow
before those variables could be used.

Now the script always returns 0 (success) and uses the output variables
to indicate whether updates were found, allowing the workflow to
complete as designed.
