fix(rustdeskserver): remove redundant else with undefined RELEASE variable

The check_for_gh_release function already prints its own 'No update
available' message when the app is up to date. The else block using
${RELEASE} was redundant and caused an empty version string to be shown
(e.g. 'already at v').

Fixes: #14267
