fix: version display picks higher of git tag vs package.json

On master branch, `git describe --tags` may find an old tag (v0.8.0)
since release tags live on the electron branch. Now both sources are
compared and the higher version wins, so package.json's synced version
(e.g. 1.0.16) is used correctly.
