docs(docs-infra): update di factory provider function to use correct parameters

This PR fixes a parameter mismatch in the `apiClientFactory` function documentation example. The factory was previously passing only http and `userService` to the ``ApiClient`` constructor, but the constructor actually requires http, `baseUrl`, and `rateLimitMs` as separate parameters.

Key Changes:

Extracts baseUrl and rateLimitMs from UserService using getter methods
Updates the ApiClient instantiation to pass all three required constructor parameters
Adds a comment explaining the assumption about UserService providing these values

(cherry picked from commit 6f716e400e)
