KeyError: 'clusters'

Describe the bug

when follow the tutorial bulk2single, the function ov.bulk2single.bulk2single_plot_cellprop raise a KeyError: 'clusters'.

To Reproduce

command:
ov.bulk2single.bulk2single_plot_cellprop(generate_adata,celltype_key='clusters')

errors:

3817 self._check_indexing_error(key)

KeyError: 'clusters'

Additional context
when use the pandas function value_counts(), the dataframe has a column named 'count' , and this key should be 'count', not 'clusters',

Sir, after testing the specific script

Fix KeyError: 'clusters' in bulk2single_plot_cellprop function

• Change ct_stat[celltype_key] to ct_stat['count'] at line 69 in omicverse/bulk2single/_utils.py to correctly reference the 'count' column created by the value_counts() method.

You may apply this change to fix until the this error is solved by the next update.
