In case the extensions has an available update and is obsolete at the same time, the uninstall button was shown twice.
An obsolete extension is not updatable; thus, the second button for the "update" action should not be shown.
Obsolete extensions are not grouped at the top of the extension page anymore and instead show an "OBSOLETE" warning text with a the "uninstall" action.
Switch to "lingui" for better DX.
Tried to persist existing languages as much as possible.
Removed "vite-plugin-node-polyfills" because it's incompatible with "lingui"
The server is not requesting these images through an extension; thus, it is not a problem to send them directly to the server since there is no problem of getting the server "stuck" due to extension rate limits.
