[tests] Fix CRLF issues in M.E.Http

Fixes: dotnet#52135

When running `Microsoft.Extensions.Http` tests on windows and
targeting `Browser`, the line ending differs between host and target
systems. Use helper `LineEndingsHelper.Normalize` method to update
expected strings.

The `Browser` Environment.NewLine is `\n`, while windows use `\r\n`.
