Retry options seem to be deprecated, but not according to the docs

TL;DR

Using retry options give warnings about the options being deprecated, but there is no mention of this in the README.

Expected behavior

Either the options should not give warnings, or the deprecation should be mentioned in the README. Ideally, the docs should be accompanied by a suggested alternate solution, because retry functionality is useful. Authentication using Workload Identity Federation sometimes fail spuriously* (which then succeeds when the workflow is rerun), so decreasing this probability with retries is a useful feature.

*= We did not see these spurious failures when authenticating with static JSON keys (which we did previously), but using static JSON keys is no longer the recommended authentication method.
