In dotnet/aspnetcore#66070 we made a decision with @danroth27 that the web worker template should be renamed to Blazor web worker template and made Blazor-specific. This change has to be followed by updates to docs.

Overview

1. Blazor on web worker doc now uses Blazor-specific template.
2. React doc now uses blazor web worker app and focus on "how to adapt it with minima changes so that it works with React". That is: editing .csproj and removing .cs JSInterop file. The changes should keep <net11 doc as it is (unless it has common parts with net11 that can be easily reused). React is lately shifting the focus to frameworks and they marked create-react-app as deprecated so we changed to Vite.
3. Release notes had the old name of the template.
