feat: upgrade to .NET 10 and improve cursor rendering logic

- Update target framework to .NET 10 in `VcrSharp.Docs.csproj`.
- Upgrade `MyLittleContentEngine.DocSite` package to version `0.0.0-alpha.0.277`.
- Enhance cursor rendering by adding conditional support for blinking based on `_options.CursorBlink`.
- Prevent unnecessary cursor animation when blinking is disabled.
