Add or more prominently link to documentation for step.retry()

[s100]

During normal usage of [email protected] I see the following repeated warning:

I.retry() is deprecated, use step.retry() instead

This comes from here, naturally.

Unfortunately I am unable to find any documentation of what step.retry() is or how to use it?

and

The documentation for retrying still uses I.retry() throughout:

Could you please add documentation for step.retry(), or if the documentation exists, could you please make it easier to find.
