chore(deps): bump all NuGet references to latest stable

[StuartMeeks]

Refreshes every out-of-date NuGet reference to its current latest stable, and keeps the release job's pinned nbgv CLI in sync with the Nerdbank.GitVersioning package version.

Package	From	To
Nerdbank.GitVersioning	3.10.85	3.10.91
Microsoft.Data.Sqlite	10.0.9	10.0.11
Microsoft.Extensions.DependencyInjection	10.0.9	10.0.11
Microsoft.Web.WebView2	1.0.4022.49	1.0.4129.50
Microsoft.Windows.SDK.BuildTools	10.0.28000.2270	10.0.28000.2526
Microsoft.WindowsAppSDK	2.2.0	2.4.0
Spectre.Console	0.57.1	0.57.2
Microsoft.NET.Test.Sdk	18.7.0	18.9.0
xunit.runner.visualstudio	3.1.5	4.0.0

Deliberately left alone

• Spectre.Console.Cli stays at 0.55.0 — still no newer stable, so the existing comment in Directory.Packages.props stands.
• xunit stays at 2.9.3 (latest stable). Runner 4.0.0 is a major bump but still runs xunit v1/v2/v3, so it pairs fine.
• The SQLitePCLRaw advisory suppression stays in Directory.Build.props — Microsoft.Data.Sqlite 10.0.11 still resolves SQLitePCLRaw 2.1.12, so the underlying condition hasn't changed.
• CommunityToolkit.Mvvm, Jdenticon-net, Markdig, Porta.Pty, the WinUI SettingsControls, H.NotifyIcon.WinUI, Velopack and coverlet.collector are all already on their latest stable.

Verification

• All 372 tests pass (Core 245, Execution 61, Importer 66).
• Full solution — including the WinUI head on Windows App SDK 2.4.0 — builds clean with 0 warnings, 0 errors on a Windows 11 host.

Visual smoke-testing of the app under Windows App SDK 2.4.0 is still worth a look before release, since a compile-clean SDK minor bump doesn't guarantee unchanged rendering.
