deps(dotnet): Bump Splat.NLog from 19.3.1 to 19.4.1

[dependabot]

Updated Splat.NLog from 19.3.1 to 19.4.1.

Release notes

Sourced from Splat.NLog's releases.

19.4.1

🔏 19.4.1 — consolidated, re-signed release

This is the recommended release. It supersedes and folds in 19.3.1, which was signed with a code-signing certificate that has since been revoked — NuGet restore fails on it with NU3012. 19.4.1 is re-signed with a valid certificate; the superseded 19.3.1 release has been removed and its notes consolidated here.

Technical Requirements and Constraints
