Hold the xunit-dotnet monorepo on 3.x until the test host is migrated

[wormeyman]

Records the refusal of #108 as a Renovate hold, so the bot stops re-proposing it every Monday.

What failed

xunit.v3 4.0.0 and xunit.runner.visualstudio 4.0.0 failed both .NET test jobs, identically on CI and on a local Mac:

Microsoft.Testing.Platform.MSBuild.targets(320,5): error : Testing with VSTest
target is no longer supported by Microsoft.Testing.Platform on .NET 10 SDK and
later. If you use dotnet test, you should opt-in to the new dotnet test experience.

xunit.v3 4.0.0 depends on xunit.v3.mtp-v2 [4.0.0, 4.0.0], which pulls Microsoft.Testing.Platform 2.x. MTP 2 drops the VSTest bridge on the .NET 10 SDK, so the current dotnet test invocation has nowhere to run.

That makes this a test-host migration rather than a version bump. The work is tracked in #111: opt the project into the new dotnet test, and replace the VSTest-only --logger "console;verbosity=normal" that both .NET jobs in ci.yml pass.

The rule

Ceiling is <4.0.0, not enabled: false, matching every other hold in the file - patches inside 3.x keep flowing and only the major is blocked. The rule carries its reason and points at #111, so the refusal travels attached to the next proposal instead of being re-derived.

Also updated: the header's hold count (six to seven) and the tracking-issue list in the packageRules comment block.

Verification

Ran the validator the file's own comment calls for, given that an unparseable config makes Renovate do nothing silently:

npx --yes --package renovate -- renovate-config-validator .github/renovate.json5
 INFO: Validating .github/renovate.json5 as global config
 INFO: Config validated successfully against 1 file(s)

Not affected

Verify.XunitV3 32.0.0 is a separate package and merged cleanly in #106 - both .NET test jobs passed on it. The Verify grouping rule above this one is untouched.
