Fix syncVersions comparing against stale submodule version

The workflow was reading Mobile-Expensify's version from the submodule
pointer (pinned commit in App's tree) instead of the latest ME main.
This caused it to always report "in sync" since the pinned version
naturally matches App. Adding `git submodule update --remote` before
the comparison ensures we check against the actual latest ME main.
