  bug: `Scalar.isin(Column)` returns a Column, not a Scalar
  ### What happened?
  
  ```python
  import ibis
  
  needle = ibis.literal(2)
  haystack = ibis.memtable({"x": [1, 2, 3]}).x
  type(needle.isin(haystack))
  # ibis.expr.types.logical.BooleanColumn
  ```
  
  ### What version of ibis are you using?
  
  main
  
  ### What backend(s) are you using, if any?
  
  _No response_
  
  ### Relevant log output
