Fix Invalid referrerPolicy error in latest versions of Chromium

[Manny651]

Calling GoToAsync without specifying a ReferrerPolicy option now raises an exception when used with the latest Chromium builds for Linux:

PuppeteerSharp.MessageException: Protocol error (Page.navigate): Invalid referrerPolicy
at Helpers.TaskHelper.WithTimeout[T](Task1 task, TimeSpan timeout, Func2 exceptionFactory) in Helpers/TaskHelper.cs:line 188
at Cdp.CdpCDPSession.SendAsync(String method, Object args, Boolean waitForCallback, CommandOptions options) in Cdp/CdpCDPSession.cs:line 113

at Cdp.CdpFrame.GoToAsync(String url, NavigationOptions options) in Cdp/CdpFrame.cs:line 95
at Cdp.CdpFrame.GoToAsync(String url, NavigationOptions options) in Cdp/CdpFrame.cs:line 106

After researching the Chromium codebase, my understanding is that CDP does not accept empty strings for the ReferrerPolicy parameter. This specific validation message seems to originate from chromium/chromium@57103b9

Thank you!

@Manny651 Don't you think we should implement this https://github.com/puppeteer/puppeteer/pull/13954/files ?

@kblok Yes, I added that same logic.
