Bringing #4873 `Localized views with Razor Pages` back to discussion for .net 7.0

> In Razor Pages, we can inject IViewLocalizer to work with localized resources - good. But sometimes, especially on content-heavy, rather static pages, it would be nice to have location specific views, i.e. MyPage.en.cshtml and MyPage.de.cshtml etc.

>My expection was that once I configure AddViewLocalization(LanguageViewLocationExpanderFormat.Suffix, ...) Razor Pages also would be resolved by their base name, but I quickly realized there might be a problem with how the corresponding PageModel should be used/resolved. I couldn't get this to work at all - is this scenario even supported with Razor Pages?

>In any case, I think the corresponding [docs](https://docs.microsoft.com/en-us/aspnet/core/fundamentals/localization) should be more explicit about what's possible with Razor Pages and potential limitations.

### Describe the solution you'd like

View location expanders should apply to Razor pages too.
