Subject: [PATCH] feat(update): add pre-release version selection prompt

Replace the single latest-release fetch in update_x-ui() with
get_releases() and select_version() functions that offer users a
choice between the latest stable and latest pre-release version,
matching the pattern already added to install.sh.
