REST API to fetch the Date of Repository Initialization or Date of First Commit

[swillis12]

Description: Requesting the ability to know either the date of the first commit or when the repository was initialized.

Requested Changes in public API:

• Changes in REST API

Expected Use Cases: In a UI when showing a date picker for selecting a commit before a certain time, this would help to disable irrelevant dates. E.g. if the repo was initialized on Aug 24, 2022, we can grey out/disable dates before that time so that the user cannot select them.

We do have an internal "property bag" for the repository (RepositoryDescription), for things that rarely change. The creation date of the repository could be stored there and exposed via a REST API
