This is a routine Renovate-generated dependency bump for the Polyfill package (10.4.0 → 10.5.0), making a single-line change to TUnit.Core/TUnit.Core.targets.

Review Summary

The change is minimal and low-risk: update the _TUnitPolyfillVersion property from 10.4.0 to 10.5.0. The new version (10.5.0) adds Regex.Count span overloads and Capture.ValueSpan — these are additive, purely compile-time polyfills with no runtime behavior changes.

No issues found. The update is safe to merge. Auto-merge is already enabled, which is appropriate for this class of dependency update.
