feat(slack): Auto-open upgrade modal for a single outdated workspace

From the integrations directory, the 'Update Now' nudge previously always
sent the user to the configurations tab. When an org has exactly one
installed workspace there is nothing to disambiguate, so append
showInstallModal=1 to the link and let useAutoOpenInstallModal open the
upgrade modal directly. Orgs with multiple workspaces still land on the
config tab to choose which workspace to update.
