Start diagnostic group_id at 1 to handle non LS diagnostics (#22694)

In particular, `DiagnosticPopover` both:

* Supports moving the selection to a diagnostic when clicked, based on
`group_id`

* Provides Diagnostic values with `group_id: 0` providing informztion on
hover about invisible characters.

So, clicking such a popover would navigate to the very first error
produced by a language server. Really not a big deal of course, but
seems good to fix as it might result in surprising behavior in other
future circumstances

Release Notes:

- N/A
