fix(cucumberjs): attach a datable to the step

[egerix]

Context

split pr #546
When I switched to allure in cucumber v8, I encountered a number of problems that were not repeated in cucumber v6:

• Attachments with the datatable are placed at the end of the test, not under the expected step. This is very unattractive if the test has several datatables. Previously, in Cucumber 6, they were placed under each step.
