Fix. Creating a Blazor project with a space in its name breaks the styling

Description

• Added a new StyleBundleName generator to the src/ProjectTemplates/Web.ProjectTemplates/content/BlazorWeb-CSharp/.template.config/template.json file. This generator uses a regex-based transformation to replace spaces in the project name with underscores for it to be aligned with the sanitized assembly name.
• Updated the src/ProjectTemplates/Web.ProjectTemplates/content/BlazorWeb-CSharp/BlazorWebCSharp.1/Components/App.razor file to use the dynamically generated StyleBundleName for the stylesheet reference, replacing the previously incorrectly bound value.

Fixes #52196

Do we know what this .1 is for? (Just surprised to see it there)

Nevermind, I think I found the commit in the history that made this change.

My theory is that this is a default name and it is through the whole template project, which will be then replaced with the user's chosen name, because folders are name like that and they get replaced with the RootName.
