[I] `BATCH_SIZE` validation error shows the literal text `{type(value))}` instead of the offending type [texera]

["eugenegujing (via GitHub)" <gi...@apache.org>]

eugenegujing opened a new issue, #7565:
URL: https://github.com/apache/texera/issues/7565

   ### What happened?
   
   When a user sets a non-integer `BATCH_SIZE` on a Python operator, the error message they get back contains the template text rather than the actual type, because the string is a plain string literal instead of an f-string and it additionally has an unbalanced parenthesis inside the placeholder.
   
   The user sees:
   
   ```
   BATCH_SIZE cannot be {type(value))}.
   ```
   
   instead of something like:
   
   ```
   BATCH_SIZE cannot be <class 'float'>.
   ```
   
   **Expected:** the message names the actual type that was supplied.
   
   ### How to reproduce?
   
   1. Add a Python UDF operator to a workflow.
   2. In its code, set a non-integer batch size, e.g.:
      ```python
      from pytexera import *
   
      class ProcessTupleOperator(UDFOperator):
          BATCH_SIZE = 10.0        # a float, not an int
   
          @overrides
          def process_tuple(self, tuple_: Tuple, port: int) -> Iterator[Optional[TupleLike]]:
              yield tuple_
      ```
   3. Run the workflow and read the error reported for the operator.
   
   Observed: `BATCH_SIZE cannot be {type(value))}.`
   Expected: the message names the supplied type, e.g. `BATCH_SIZE cannot be <class 'float'>.`
   
   Directly, without a workflow: call the validator with a float and inspect the `ValueError` message.
