Re-runs `dotnet format analyzers --diagnostics NUnit2046 NUnit2045` after
the Tier 2 Assert.Multiple wrap, which exposed:
- `Has.Length.EqualTo(n)` rewrites for `string[]`/array `.Length` checks
(the first pass only knew about `.Count`).
- `Is.Not.Empty` rewrites for `Count, Is.GreaterThan(0)`.
- A handful of new NUnit2045 groups that became wrappable once the
initial Multiple blocks settled the surrounding indentation.
Tests still 1180/1180 passing.
