feat: Support Sso for SharePoint bot ACEs

[bentsai10]

Fixes
This change allows SharePoint Bot Driven Aces to use SSO.

Description
Currently a bot driven ace in SharePoint can only use the magic code flow. This flow is not ideal as it requires a user to copy and paste a code from a different window or at a minimum we get flicker of the window being shown. This change allows us to use the SSO flow so that not authentication prompts are shown.

#minor

Specific Changes
Adds a new cardExtension/token activity for doing a token exchange.

@ceciliaavila and team. Can you review this PR and look into the test failures?

I believe this should bring JS SDK to parity with Dotnet for Sharepoint.

@ceciliaavila Bumping this one for help with unblocking, thank you!

[ceciliaavila]

The changes look good. I just mentioned some small details.
@tracyboehrer, the test check failed with a transient error in the coverage step. The tests passed.

@ceciliaavila Addressed your comments, thank you!

[bentsai10]

@ceciliaavila @tracyboehrer How can we override/resolve the transient error?
