hey @Horsty80 thanks for your contribution!

So just let you know the documentation fixes would be not as simple as we see.

sometimes you need to visit https://github.com/codeceptjs/CodeceptJS/tree/3.x/docs and find the relevant changes there, sometimes the changes are at JSDocs of helper itself.

After making changes, you shall need to run npm run docs to make the docs sync everywhere.
