Add show_as_button to ConnectionBase.cs

[dylanAtWork]

Changes

show_as_button is missing from Connections in auth0.net but it exists in dumps from the deploy-cli as well as in other Auth0 packages like go-auth0. This PR adds it to ConnectionBase.cs

References

go-auth0 mentioned above:
https://github.com/auth0/go-auth0/blob/a98b898932cd024335fba6971c8a9d6853e9493c/management/connection.go#L129

I've got an application using this workaround for the time being:

    public class FixedConnectionCreateRequest : ConnectionCreateRequest
    {
        [JsonProperty("show_as_button")]
        public bool? ShowAsButton { get; set; }
    }

Testing

Please describe how this can be tested by reviewers. Be specific about anything not tested and reasons why. If this library has unit and/or integration testing, tests should be added for new functionality and existing tests should complete without errors.

A good test to me would probably be to create a Connection with show_as_button set, or making a GET for an existing one

I don't see this property being listed in the API docs:

• https://auth0.com/docs/api/management/v2/connections/get-connections
• https://auth0.com/docs/api/management/v2/connections/post-connections
• https://auth0.com/docs/api/management/v2/connections/patch-connections-by-id

I have reached out internally to understand why that property isn't documented. Typically it means that it should be used publicly, and should not be part of our SDK(s).

However, I will get back to this once I have more information.

That's odd, it's something new with Universal Login I think so maybe it was just missed?

it corresponds with this in the Admin UI

Thanks for the PR, sorry it took so long but I needed to get some information internally.

We will need to circle back to update XML docs here, but will merge.
