Updates for WebSharper 8

[Jand42]

Updates since WebSharper 6:

• Web and SPA projects have vite configured for Debug mode, esbuild for Release mode. They use separate bundles for Home and About pages via the Content.Page parameter, although by default, the About page has no dynamic content, so it will come up without a WS script tag
• Html projects use esbuild
• settings have been simplified, obsolete settings UseMinifiedScripts, UseStdlibCdn are removed. Removed unused appsettings.Development.json files
• there is a new setting ScriptRedirectUrl in appsettings.json for vite url, this is only accessed in Debug mode

Template updates:

• C# Html template have been updated to match the same as Web and also F# Html template
• In Html templates, adjusted text to reflect we are not sending calculation to the server, but locally ("Client calculated response" instead of "Server response")
