Implement SignInWithSso

[Rycko1]

What kind of change does this PR introduce?

Port the SignInWithSso functionality from the supabase auth js library into the csharp implementation found here

Bug fix, feature, docs update, ...

What is the current behavior?

#93

What is the new behavior?

Added SignInWithSSO functionality to both the API and Client layers. I skipped adding it to the stateless client because without making the HTTP request to the provider, there is no simple way to generate a stateless Url that can be used for authentication. If someone else can find a solution to this feel free to modify my code and pull request :)

I also added relevant error codes and handlers for any returned error related to SSO

Additional context

An example of a request once SSO is configured from the CLI and added to my supabase project

My apologies for taking so long to get back to you, it’s been quite a busy week. I’ll hopefully take a look at this in either the afternoon or over the weekend. Your work is much appreciated!

Wonderful work @Rycko1! Very clean and clearly documented. If you have the chance, I'd love to have an example added to the wiki here (https://github.com/supabase-community/supabase-csharp/wiki/Authorization-with-Gotrue).

Otherwise, excited to include this in the next release!

I did rename to SignInWithSSO since it's an acronym and to match the JS client - available in [email protected]

No worries at all! :) Glad I could help
