f34: Add i3, i3-extended, i3-desktop-environment COMPs
This commit makes three new additions to the Fedora 34 comps file:
1. Adds `i3` package group: Minimal, base set of packages required to
run the i3 window manager
2. Adds `i3-extended` package group: Supplemental, optional packages for
advanced users who want several different tools available to use
3. Adds `i3-desktop-environment` environment: Groups together a base
system similar to other desktop environments.

i3: Address @adamw and @ngompa feedback in fedora-comps#569
This is a follow-up that addresses the following feedback:
1. Remove deprecated category for i3-desktop-environment
2. Change "i3 Workstation" to "i3 desktop" in Anaconda
3. Add lightdm-gtk as default greeter for lightdm-greeter
This should now be ready to merge.
