Feature Request: Support POST to recents API to update recents list

[tcobbs-bentley]

The current API includes queryRecentsAsync, which uses the itwins/recents GET REST API to get the most recently used iTwins (up to 25). This list isn't particularly useful if there is no way to indicate that an iTwin has been used, so it would be great if a new API function (like addRecentAsync) were added to use the itwins/recents POST REST API to add an iTwin ID to the list of recently used iTwins.

I may be able to work out how to do this myself. If so, I will submit a PR.

This is also needed for our team, currently we're doing it outside itwins-client. It would be nice if this could be added to ITwinsAccessClient api
