who cares enough to track down what marked.js is doing.

Not currently required, but allows plugins to optionally use features from
libportal to access desktop features.

We probably need to figure out how we want to use these things and stay
compatible with other platforms like macOS in the future.

Also cleanup `gbp_buildui_pane_diagnostic_tooltip()` so it mimics the
pattern in `plugins/todo` and `libide/tree`.

When starting a build stage `on_build_stage_query()` would crash when
the `IdeSubprocessLauncher` had a command line of more than 2 items and
none of those were ninja or ninja-build.

Found the crash when using a jhbuild pipeline, since its argv is
`jhbuild run ninja`, the first loop got stuck on comparing `jhbuild`
against ninja, ninja-build, and then infinity.

The above because `g_strv_contains()` expects NULL terminated arrays,
otherwise it will start accessing random memory and likely crash.

Fixes #1246

This has to do with diagnostic generation, so make that more clear.
