The name of web root folder should be configurable

Commit reference: 872287f

In ASP.NET Core:

1. The name of web root folder can be configured using IWebHostEnvironment.WebRootPath property.
2. Static files can be served outside of web root path.

Thus, Uno Wasm Bootstrap should not force wwwroot to be added at the end of the publishing path.

We have several Uno applications that are configured to publish to the appropriate folders in our build pipeline (without specifying wwwroot in the path). Now, after upgrading from version 7.0.x, everything is broken...

@mmarinchenko We do not have a change available to get this out of the current structure from what ASP.NET does. It may be modifiable when the bootstrapper will move to net9.
