This works around the issue where browsers installed as snap package
can't access files under `$HOME/.local`. Instead we now only open
external links with the browser. Local non-html files we open with
the default app, and links to local html file we open in webview
(like we did previously with `welcome.htm` files).
Fixes#9600.
- Remove "package" from the tooltips text since that might be
confusing to users.
- Also make title of Welcome (Help) dialog optionally say "installed"
instead of always so that we open that dialog via the Help button
we just display the keyboard name.
- Refactor Keyboard Details dialog to remove an unnecessary box.
- Add padding after keyboard details in Keyboard Details dialog.
