feat(sway-autostart): drop dex in favor of using autostart_applications config

The firewall-applet is failing to launch with dex (it core dumps because it can't use "wayland" for QT_QPA_PLATFORM), and nm-applet is already being launched from the autostart_applications config, so the only thing dex is actually doing is starting the Welcome App.

This commit drops dex in favor of setting all apps that need to be autostarted in the Sway config, where there is more flexibility with setting needed environment variables or making other adjustments. Additionally, this configuration choice will not inherit conflicts from other autostart processes if users are running multiple environments (see https://github.com/EndeavourOS-Community-Editions/sway/pull/84).
* Remove dex from packages-repository.txt and from autostart_applications config
* Add firewall-applet and eos-welcome to autostart_applications config
