Launch Default i3 Session

To do so on Ubuntu, run sudo apt install i3-gaps-session to add an option on login that starts vanilla i3-gaps without regolith.

Use Case

This is useful for, say, running an application that does not integrate well with GNOME. For example, Spotify’s unmaintained official Linux client mishandles its file selection dialogue and crashes when

1. Setting user profile photo
2. Setting album cover photo
3. Adding a local directory to the library paths

under GNOME and Regolith. Switching to vanilla i3 solves the crash.
