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

[s100]

During normal usage of codeceptjs@3.7.2 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.

[mirao]

It's in the release notes for 3.7.0: https://codecept.io/changelog/?#%F0%9F%A5%BE-step-options (but I didn't test it).
You're right it's missing in official docs.
