text: Title: Use `assing`, not `variable`, with FOR and TRY/EXCEPT model objects when referring to assigned variables
  Body: # FOR 
  After tokenising the assigned variable is of type `VARIABLE` with FOR loops but shall be `ASSIGN`:
  
  Example:
  ```robot
  FOR     ${i}    IN RANGE   10       # ${i} is:  token.type == "VARIABLE"
     Log    ${i}
  END
  ```
  
  Here is an assignment happening as in:
  ```robot
  ${i}    Set Variable     1
  ```
  
  Therefore `VARIABLE` would be considered "wrong" here.
  
  
  # TRY/EXCEPT
  
  Similar situation is with EXCEPT AS variables. they are also `VARIABLE`
  
  Example:
  ```robot
  TRY
      Fail     failure message
  EXCEPT     AS    ${error}     # ${error} is:  token.type == "VARIABLE"
     Log     my error ${error}
  END
  ```
  
  Should also be `ASSIGN` after the AS
