Fix 16840: Navigate to special URLs without throwing errors (#26769)

### Summary
Allow the [manual] navigation to special URL like `https://localhost:5001?keyword=你好 世界`


### Details
`Uri.IsWellFormedUriString` does not tell you whether the URL is valid or not instead it tells if the URL needs to be escaped to further work with it [At least that's how it is currently described and implemented].  To know if a URL is valid `Uri.TryCreate` will do correct job, for additional information please check [Runtime#37634](dotnet/runtime#37634)

ℹ For consideration, other [places in the repo](https://github.com/dotnet/aspnetcore/search?q=Uri.IsWellFormedUriString) might have the same problem.
