Subject: fixes #22284; fixes #22282; don't override original parameters of
 inferred lambdas (#23368)

fixes #22284
fixes #22282


```
Error: j(uRef, proc (config: F; sources: auto) {.raises: [].} = discard ) can raise an unlisted exception: Exception
```


The problem is that `n.typ.n` contains the effectList which shouldn't
appear in the parameter of a function defintion. We could not simply use
`n.typ.n` as `n[paramsPos]`. The effect lists should be stripped away
anyway.
