erroranalysis: Fix the scenario when samples in dataset and string_indexed_data don't match

[gaugup]

Description

For large data scenario, if the test set in provided at run time (after cohort filtering) it could have different number of samples than the test data used at the RAI computation time. The error analysis tree computation is such cases can fail with the following error:-

index 100 is out of bounds for axis 0 with size 100
Traceback (most recent call last):
  File "c:\users\gaugup\documents\github\responsible-ai-toolbox\raiwidgets\raiwidgets\responsibleai_dashboard_input.py", line 174, in debug_ml
    max_depth, num_leaves, min_child_samples)
  File "c:\users\gaugup\documents\github\responsible-ai-toolbox\erroranalysis\erroranalysis\analyzer\error_analyzer.py", line 367, in compute_error_tree_on_dataset
    min_child_samples=min_child_samples)

  File "c:\users\gaugup\documents\github\responsible-ai-toolbox\erroranalysis\erroranalysis\_internal\surrogate_error_tree.py", line 318, in get_surrogate_booster_local
    input_data[:, c_i] = analyzer.string_indexed_data[row_index, idx]
IndexError: index 100 is out of bounds for axis 0 with size 100

The fix is to compute string_indexed_data if the number of dataset samples is different from string_indexed_data.
