Fixes #36514
**Description:**
This change enhances the `collect` function in
`apache_beam.runners.interactive.interactive_beam.py` to provide an option for
retrieving raw data elements.
**Fix/Changes::**
This change implements the following:
1. **Modified `interactive_beam.py`:**
* Added a new boolean argument `raw_records` (defaulting to `False`)
to the `ib.collect()` function signature.
* When `raw_records` is set to `True`, the `collect` function now
bypasses the `elements_to_df` conversion and returns a tuple of lists (or a
single list if only one PCollection is provided and `force_tuple` is `False`),
containing the raw elements from the PCollection(s).
2. **Modified `interactive_beam_test.py`:**
* Added several new test methods to the `InteractiveBeamTest` class to
cover the new `raw_records` functionality:
* `test_collect_raw_records_true`: Verifies list output with
`raw_records=True`.
* `test_collect_raw_records_false`: Verifies default
DataFrame-like output.
* `test_collect_raw_records_true_multiple_pcolls`: Checks list
outputs for multiple PCollections.
* `test_collect_raw_records_false_multiple_pcolls`: Checks
DataFrame-like outputs for multiple PCollections.
* `test_collect_raw_records_true_force_tuple`: Checks interaction
with `force_tuple=True`.
* Assertions in tests for `raw_records=False` were modified to check
for non-list types and the presence of DataFrame-like attributes (e.g.,
`.columns`, `.values`) to avoid requiring a direct `import pandas as pd` in the
test file.
These changes provide users with more flexibility in how they retrieve and
work with data from PCollections in interactive environments.
