Code Review: chore(deps): update dependency polyfill to 9.10.0

This is a straightforward minor dependency bump of Polyfill from 9.9.0 → 9.10.0.

Change Summary

The single change is in TUnit.Core/TUnit.Core.targets, updating the _TUnitPolyfillVersion property from 9.9.0 to 9.10.0.

Assessment

No issues found. This is a minimal, low-risk dependency update:

• The change is isolated to a single MSBuild property in .targets
• Polyfill is a compile-time source generator — it injects polyfill types only when targeting older frameworks (netstandard2.0, netstandard2.1, .NETFramework), so runtime behavior is not affected for net8.0/net9.0/net10.0 targets
• It's a minor version bump, so it should be backwards-compatible by semver convention
• Automerge is already enabled, which is appropriate for this class of automated dependency update

LGTM. Safe to merge.
