Remove favicon.ico from Identity scaffolding

[Copilot]

Identity scaffolding currently adds favicon.ico to wwwroot/, conflicting with existing favicons in Blazor WebAssembly and other projects.

Changes

• Removed favicon.ico entry from Bootstrap 4 and Bootstrap 5 identity generator file configurations
• Deleted favicon.ico template files from both Bootstrap template directories

Applications with existing wwwroot/favicon.ico files will no longer experience conflicts when scaffolding Identity. Projects without a favicon can add one independently.

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• kijvsblobprodcus387.vsblob.vsassets.io
  • Triggering command: /usr/bin/dotnet dotnet build src/Scaffolding/VS.Web.CG.Mvc/VS.Web.CG.Mvc.csproj (dns block)
• tphvsblobprodcus375.vsblob.vsassets.io
  • Triggering command: /usr/bin/dotnet dotnet build src/Scaffolding/VS.Web.CG.Mvc/VS.Web.CG.Mvc.csproj (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
