modified documentation to not use DataConverter incorrectly

[Krashcan]

What changed? Documentation for Worker constructor

Why? It incorrectly mentioned that things like DataConverter are being passed via options which is no longer the case since release v3.0.0.

How did you test it? No actual code change done

Potential risks Nothing, worst case my documentation itself is incorrect.

Release notes No

Documentation Changes No
