Update runtimecompilation to version 6.0.9 (ensure hot reload continues to work for cshtml)

[dotnetshadow]

Update Microsoft.AspNetCore.Mvc.Razor.RuntimeCompilation to 6.0.9

This ensures that dotnet watch hotreload functionality continues to work when editing a .cshtml file. Any version below 6.0.5 breaks this.

Alternatively
You could just remove RuntimeCompilation since it's not needed anymore in .net 6

Actually I'm not sure if this is working or not anymore. I think RuntimeCompilation needs to be removed for it to work in a hot reload situation

Can you see if this is a major/minor version upgrade and then change the version accordingly here
