chore: bump submodules

[jokeyrhyme]

• ran git submodule foreach --recursive 'git fetch; (git checkout master_jammy || git checkout master); (git pull origin master_jammy || git pull origin master);'
• ran rm -rf ~/.cargo/git ~/.cargo/registry and just clean to make sure I was testing against currently-available commits in GitHub and not something I had cached locally
• confirmed that just sysext still works
• end-to-end test from cosmic-greeter into cosmic-session, running Firefox-in-flatpak to create this PR (works)
• one odd thing I've noticed is that cosmic-term doesn't seem to work when loading it from launcher/desktop, but does load when running it from within alacritty, and there's nothing in journalctl to suggest why

[jokeyrhyme]

• okay, the issue is cosmic-greeter versus cosmic-term, because I can't reproduce the issue when starting the test from gdm
• I'll raise an issue against cosmic-greeter because I believe it's an environment variable thing

[jokeyrhyme]

• I narrowed my cosmic-greeter versus cosmic-term issue down to the wgpu crate having problems with AMDVLK on my system (I have an AMD iGPU and an AMD dGPU, and AMDVLK has poor support for the iGPU)
• my shell profile sets AMD_VULKAN_ICD=RADV, but this doesn't take effect in greetd the same way it does via gdm
• AMD_VULKAN_ICD=AMDVLK cosmic-term fails, and AMD_VULKAN_ICD=RADV cosmic-term works
• I think use login shell rather than reading ~/.profile cosmic-session#23 would fix this on my system, but I have other work arounds
