Subject: [PATCH] statistics: Fix geometric_mean() error message for negative
 inputs

The error message was constructed with two positional arguments to
StatisticsError, causing str(e) to display as a tuple:
"('No negative inputs allowed', -2.0)". Use an f-string instead so
the value is embedded directly in the message string.
